Experimental and theoretical results for a two‐dimensional metal photonic band‐gap cavity
TLDR
In this paper, the authors demonstrate that a two-dimensional lattice of metal cylinders can form a complete photonic band-gap (PBG) structure, which exhibits a single broad PBG extending from zero frequency to a threshold frequency, above which all modes may propagate in some direction.Abstract:
We demonstrate, by both microwave experiments and numerical simulation, that a two‐dimensional lattice of metal cylinders can form a complete photonic band‐gap (PBG) structure. The band structure exhibits a single broad PBG extending from zero frequency to a threshold frequency, above which all modes may propagate in some direction. A single cylinder removed from the lattice produces a defect mode localized about the defect site, with an energy density attenuation rate of 30 dB per lattice constant. The frequency dependence of the transmission through a finite thickness of this structure is also calculated in good agreement with the measurements. We suggest that the defect mode resonant cavity when formed by appropriate low loss metals may be advantageous for use in PBG high energy accelerator structures that we are evaluating.read more

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.

Photonic band gaps for arrays of perfectly conducting cylinders
TL;DR: The photonic band structures for very dilute arrays, where they tend towards the expected free-propagation form, are exhibited and very interesting diferences between 8 and p polarization behavior are manifest.

Photonic band gaps and defects in two dimensions: Studies of the transmission coefficient
TL;DR: This technique has been applied to cases where the plane-wave method fails or becomes too time consuming, such as when the dielectric constant is frequency dependent or has a nonzero imaginary part, and when defects are present in an otherwise periodic system.
