Electronic Bandgap Materials

New for May 2011! Electronic band gap, (sometimes referred to asphotonic band gap, or frequency selective surfaces) has been well documented in the past for various applications. UCLA has done extensive research with regard to antenna applications. South Dakota School of Mines is another college doing research in this important area. EBG might just be the opposite of a career killer!

UCSD recently hired Dan Sievenpiper, the inventor of the high-impedance surface. Sievenpiper's mushroom surface represented the first practical use of electronic bandgap structures. He was issued many patents on this when he was at HRL Laboratories.

The marvels of electromagnetic band gap structures include frequency selective surface (FSS) structures, surfaces with perfectly magnetic conducting properties (PMC), materials with negative permittivity and negative permeability.

More to come!
