Journal ArticleDOI
High-impedance electromagnetic surfaces with a forbidden frequency band
TL;DR: In this paper, a new type of metallic structure has been developed that is characterized by having high surface impedance, which is analogous to a corrugated metal surface in which the corrugations have been folded up into lumped-circuit elements and distributed in a two-dimensional lattice.
Proceedings ArticleDOI
High-impedance electromagnetic ground planes
Lijun Zhang,Eli Yablonovitch +1 more
TL;DR: In this paper, a new type of metallic electromagnetic structure has been developed that is characterized by having high surface impedance, which is made of continuous metal and conducts DC currents, but does not conduct AC currents within a forbidden frequency band.
Journal ArticleDOI
Thin frequency-selective lattices integrated in novel compact MIC, MMIC, and PCA architectures
TL;DR: The design of novel composite materials for ICs and printed circuit antenna (PCA) applications is analyzed and optimized, emphasizing crosstalk suppression, circuit-coupling tailoring, and gain enhancement.
Proceedings ArticleDOI
An efficient finite-element method for the analysis of photonic band-gap materials
TL;DR: In this article, an efficient finite element method (FEM) is presented to calculate the bandgap information of photonic bandgap (PBG) materials, which is essential for the design of various practical applications using PBG materials.
Proceedings ArticleDOI
Microstrip line fed slot antenna with PBG superstrate
TL;DR: In this article, the effect of using a superstrate PBG material on a microstrip line fed slot antenna is investigated, where the PBG layer is composed of periodic metallic blocks inside a host dielectric material with high material permittivity and exhibits a complete bandgap at the design frequency of the slot antenna.
