Solution of Extremely Large Integral Equations in Computational Electromagnetics (with Fast Algorithms and Parallel Computing)

We are pleased to announce that Distinguished Lecturer Levent Gürel is flying out from Turkey to speak to the IEEE AP-S Society of Boston on April 17 at 6pm

Abstract:

Accurate simulations of real-life electromagnetics problems with integral equations require the solution of dense matrix equations involving millions of unknowns. Solutions of these extremely large problems cannot be achieved easily, even when using the most powerful computers with state-of-the-art technology. Some of the world’s largest integral-equation problems in computational electromagnetics have been solved at Bilkent University Computational Electromagnetics Research Center (BiLCEM). Most recently, we have achieved the solution of 550,000,000x550,000,000 dense matrix equations! This achievement is an outcome of a multidisciplinary study involving physical understanding of electromagnetics problems, novel parallelization strategies (computer science), constructing parallel clusters (computer architecture), advanced mathematical methods for integral equations, fast solvers, iterative methods, preconditioners, and linear algebra.

In this seminar, following a general introduction to our work in computational electromagnetics, I will continue to present fast and accurate solutions of large-scale electromagnetic modeling problems involving three-dimensional geometries with arbitrary shapes using the multilevel fast multipole algorithm (MLFMA) and parallel MLFMA. Some of the complicated real-life problems (such as, scattering from a realistic aircraft) involve geometries that are larger than 1000 wavelengths. Accurate solutions of such problems can be used as reference data for high-frequency techniques. Solutions of extremely large canonical benchmark problems involving sphere and NASA Almond geometries will be presented, in addition to the solution of complicated objects, such as metamaterial problems, red blood cells, and dielectric photonic crystals. Solving the world's largest computational electromagnetics problems has important implications in terms of obtaining the solution of previously intractable physical, real-life, and scientific problems in various areas, such as (subsurface) scattering, optics, bioelectromagnetics, metamaterials, nanotechnology, remote sensing, etc. For more information, please visit www.cem.bilkent.edu.tr.

COURSE SUMMARY

Are you interested in learning about radar by building and testing your own imaging radar system?

MIT Professional Education is offering a course in the design, fabrication, and test of a laptop-based radar sensor capable of measuring Doppler and range and forming synthetic aperture radar (SAR) imagery. Lectures will be presented on the topics of applied electromagnetics, antennas, RF design, analog circuits, and digital signal processing while at the same time you build your own radar system and perform field experiments. Each student will receive a radar kit, designed by MIT Lincoln Laboratory staff, and a course pack.

Please help select speakers for 2012

Hello IEEE APS Boston community members,

It is the new year and we are in the process of inviting several exciting and interesting speakers for our monthly meetings. We have the opportunity of inviting two distinguished lecturers every year from the IEEE AP-S Distinguished Lecturer Program and I need your help selecting the two we should invite this year. The list of lecturers can be found at "http://www.ieeeaps.org/distlectureres.html". Please send me an email with your top two candidates before the end of February.

Also If you are interested in presenting you work to the community or if you have a speaker in mind please let me know at ojunior82@gmail.com.

We already have Nathan Cohen, CEO of Fractal Antenna Systems scheduled for May.

Best,

Raoul Ouedraogo

2012 IEEE INTERNATIONAL SYMPOSIUM ON ANTENNAS AND PROPAGATION AND USNC-URSI NATIONAL RADIO SCIENCE MEETING

WE CORDIALLY INVITE YOU TO ATTEND THE

2012 IEEE INTERNATIONAL SYMPOSIUM ON ANTENNAS AND PROPAGATION

AND

 USNC-URSI NATIONAL RADIO SCIENCE MEETING

Dear Colleagues and Friends,

On behalf of the IEEE Antennas and Propagation Society and USNC-URSI, the Steering Committee invites you to attend the joint 2012 IEEE International Symposium on Antennas and Propagation and USNC-URSI National Radio Science Meeting in Chicago, Illinois, USA.  The Steering Committee has been working hard to plan an innovative and rewarding technical meeting with numerous opportunities to interact and collaborate with other participants.  We also welcome you to bring your families to Chicago, a very family-friendly city, served by two major airports, O’Hare International Airport and Midway International Airport.

We represent the premier international venue in the field of antennas and propagation. Our robust technical program is corroborated by many workshops and short-courses. In 2012, a Plenary Session, featuring excellent speakers highlighting the state of the art and emerging areas of research, will inaugurate the technical sessions.  All technical papers must be submitted no later than January 17, 2012 and should comply with the requirements outlined in the Technical Program section of the website.  The IEEE AP-S is sponsoring a student paper contest and a student design contest.

The meeting will be formally inaugurated on July 8, 2012, with a reception at the Art Institute of Chicago, the United States’ second largest art museum. The reception will be in the stunning and recently opened Modern Wing, designed by Pulitzer-Prize winning architect Renzo Piano. The Modern Wing houses the museum’s modern European paintings and sculptures, contemporary art, architecture and design, and photography.  If there is sufficient registration in advance, the Art Institute will put on an educational program for children of participants during the opening reception. 

The Steering Committee also is working on a social program that celebrates the vibrance and diversity of Chicago, the third largest city in the United States.  The Social Program is intended to appeal to participants and their family members of all ages. Chicago’s great magic lies in its mix: sophisticated yet friendly, bustling city streets adjacent to long stretches of green parks and sparkling blue Lake Michigan, and a stunning year-round array of things to see and do unique in all the world. For those who also like to explore on their own or for participants who would like to stay a few extra days to see the city, Chicago is more walkable than most global cities, and visitors of all ages enjoy the proximity of such attractions as Navy Pier, Millennium Park, Art Institute of Chicago and other treasures. The city’s performance art scene delivers theatre, music and dance in historic venues. And, of course, an endless assortment of restaurants, shopping and nightlife are all at your fingertips, ready to match every taste, budget and mood.  Highlights of Chicago and sample two-day and six- day itineraries of activities, in eight different languages, can be found on the Chicago Information pages of this website.

The Sheraton Chicago Hotel and Towers, the conference venue, is the premier convention and business hotel in the Midwest. With over 15 years of award-winning service, it offers 1,209 guest rooms and state-of-the-art meeting space. The hotel, overlooking the Chicago River, is ideally located in the heart of downtown Chicago and is within walking distance of Navy Pier, the Magnificent Mile, Millennium Park, the Loop business district, the Art Institute, and much more. 

We would like to make this event as technically rewarding and enjoyable as possible, so please do not hesitate to contact the appropriate member of the Steering Committee with any suggestions and ideas.  We welcome your input. 

Adapting a line from Frank Sinatra’s famous song, we want to make Chicago your kind of town.  We look forward to seeing you in Chicago in July 2012.

Best regards,

Danilo Erricolo

General Chair of the 2012 Steering Committee
