Metamaterials for Miniaturization of Narrowband and Ultra-Wideband Antennas

Please join the IEEE AP-S Boston Chapter for a special holiday seminar from distinguished lecturer John Volakis, Director of the legendary OSU Electro-Science Laboratory at Ohio State University.

Volakis will present his research on "Metamaterials for miniaturization of narrowband and ultra-wideband antennas."

This talk will be held on Monday December 6, at 6pm in the
MIT Lincoln Laboratory A-Café, 244 Wood Street, Lexington, MA. For directions please see:

Please feel free to invite your friends, it is sure to be an enjoyable
evening full of radar, antenna, signal processing, and sensing

It is well-recognized that materials design holds promise in developing novel antennas that are much smaller and allow greater multi-functionality than ever before. Such needs stem from the unprecedented growth of wireless communications and related research that is highly fueled by growth in commercial and defense multi-band and high bandwidth future communication systems. This presentation will discuss how modified materials, inductive/capacitive lumped loads and low loss magnetic materials/crystals (Metamaterials) are impacting antenna design with the goal of overcoming miniaturization challenges (viz. bandwidth and gain reduction, multi-functionality etc.). Dielectric design and texturing has, for example, led to significant size reduction and higher bandwidth for low frequency antennas. Also, recent magnetic photonic crystals (MPCs) and non magnetic versions of these crystals hold a promise for antenna/array miniaturization. Formal design methods incorporating local, global or hybrid optimizers for antenna and their radio frequency (RF) applications will play a critical role in materials design. Practical realizations of these new materials are poised to challenge computational and design methods for a variety of RF applications.
