IEEE Antenna & Propagation; Microwave Theory & Techniques; and Aerospace & Electronic Systems and Electron Devices Societies Lecture Series

Dr. Nathan Cohen, CEO of Fractal Antenna Systems Inc will give a seminar on fractal antennas and RF cloaking with live demo.

Date: Thursday, October 25, 2012                          Time: 6:00 PM

Location: MIT Lincoln Laboratory A-Café             Refreshments served at 5:30pm

TITLE: You Can Do That? Twenty Five Years of Fractal Antennas
  

Abstract: This year marks the 25th year of the creation and recognition of fractal antennas as a new and worthwhile class of antenna design. Despite this longevity, published summaries remain poor in accuracy and detail, although fractal antenna advantages are unrealized with other design approaches. This talk presents a variety of ways in which fractal antenna technology (including fractal resonators and fractal metamaterials) has been used to produce: smaller, multiband antennas without components; wideband invariant antennas with huge bandwidths; sparse array that are frequency invariant and low in sidelobes; lower profile antennas with better performance on metal; extremely low RCS radar targets; fractal metasurface wideband radiators; wideband invisibility cloaks; rapid convergence design algorithms; and so on. I will also debunk claims about electrically small antennas; 'ecumenical' antenna performance; and so on, which have prevented more rapid progress in fractal antenna acceptance in the United States. A live demonstration will also be shown.

 

Bio: Nathan Cohen is the CEO of Fractal Antenna Systems, Inc. of Waltham, MA. He is the founder of fractal antenna technology and holds over 2 dozen patents on them. Previously he was an academic radio astronomer and physicist who retired as a professor from Boston University in 2002. He holds a Ph.D. from Cornell University and conducted his thesis work at Haystack observatory on Very Long Baseline Interferometry (arrays) and gravitational lenses. He has authored over 80 papers and 3 books.

Low-Cost Ultrawideband (UWB) Phased Array Antennas - Importance, Challenges and Inroads

We are pleased to announce that Prof. Marinos N. Vouvakis from University of Massachusetts Amherst will present to the Microwave Theory & Techniques and the Antennas & Propagation Societies On April 19 at 6pm

Abstract:

The two prevailing trends in modern communication and sensing system technologies are increased information throughput or functionality, and smaller sizes. From the physical-layer electronics perspective such as RF/microwave engineering, these trends translate into hardware with wider bandwidths and higher frequencies of operation. Yet, when it comes to the design of antenna arrays, that are necessary in every wireless communications, stand-off sensing or electronic countermeasure, these treads are in direct conflict with one another. Ultrawideband (UWB) phased arrays are significantly more challenging to design and build than their narrowband counterparts, whereas manufacturability constraints above X-band severely limit the effectiveness of bandwidth enhancement methods. These technical challenges are reflected in the skyrocketing price-tags of extremely high frequency (EHF) UWB arrays, and their limited use to select military or security applications.

Established UWB phased array technologies such as the Vivaldi array, or the fragmented aperture array or Monk’s current sheet array are either too complicated to build at EHFs, or require performance-limiting feeding methods to integrate with the rest of the phased array system, or cannot be easily installed or maintained due to lack of aperture modularity. This seminar will introduce a novel low-cost UWB phased array, the planar ultrawideband modular antenna (PUMA) that overcomes all these limitations. The PUMA array is extremely simple, making it easy to build with standard low-cost microwave fabrication techniques even above Ku-band, the key comes from its novel direct-feeding scheme that avoids altogether external baluns and elaborate feed-line shielding without performance degradation. Moreover, the carefully laid-out PUMA aperture allows for modular manufacturing with tiled assemble, leading to certain cost, installation, maintenance and robustness benefits.

After a brief introduction in ultrawideband/multifunctional systems and phased arrays, the talk will focus on the basic PUMA array topology, variations, principles of operation and modeling, and design and manufacturing approaches. The design, fabrication and measurements of an exemplary 7-21GHz PUMA design will be used to concretely demonstrate the technology. Several newer computational prototypes will be presented that operate at higher than 6:1 bandwidth. Important phased array aspects such as impedance matching (VSWR), coupling, radiation pattern, wide angle scanning, polarization purity, and fabrication cost will be used to scrutinize the quality of the designs. Time permitting, a short glimpse of the advanced in-house numerical modeling techniques, used to design the full finite PUMA array will be given.

Vouvakis (S'99, M’05) is an Associate Professor of Electrical and Computer Engineering (ECE) at the University of Massachusetts Amherst, where he conducts research and teaching in the areas of microwave and antenna engineering, and computational electromagnetics.

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.
