Two-dimensional microwave band-gap structures of different dielectric materials
TLDR
In this paper, the use of low dielectric constant materials to form two-dimensional microwave band-gap structures for achieving high gap-to-midgap ratio was reported.Abstract:
We report the use of low dielectric constant materials to form two-dimensional microwave band-gap structures for achieving high gap-to-midgap ratio. The variable parameters chosen are the lattice spacing and the geometric structure. The selected geometries are square and triangular and the materials chosen are PTFE (e = 2.1), PVC (e = 2.38) and glass (e = 5.5). Using the plane-wave expansion method, proper lattice spacing is selected for each structure and material. The observed experimental results are analyzed with the help of the theoretical predictionread more

Microstrip microwave band gap structures
TL;DR: In this paper, microstrip-based microwave band gap structures are formed by removing the substrate material in a periodic manner, and these structures can serve as a non-destructive characterization tool for materials, a duplexor and frequency selective coupler.

A simple and efficient method to design electromagnetic band gap grids
TL;DR: In this paper, a simple design method for behavior of metamaterials of metallic rods is presented, and experimental results of the method are given. But this method is not suitable for the case of metal rods.

Inhibited Spontaneous Emission in Solid-State Physics and Electronics
TL;DR: If a three-dimensionally periodic dielectric structure has an electromagnetic band gap which overlaps the electronic band edge, then spontaneous emission can be rigorously forbidden.

Photonic band structure: The face-centered-cubic case.
TL;DR: This work has identified one particular dielectric ``crystal'' which actually has a ``photonic band gap'' and requires a refractive index contrast greater than 3 to 1, which happens to be readily obtainable in semiconductor materials.

Photonic band structure of two-dimensional systems: The triangular lattice
Martin Plihal,A. A. Maradudin +1 more
TL;DR: By the use of a position-dependent dielectric constant and the plane-wave method, the photonic band structure for electromagnetic waves in a structure consisting of a periodic array of parallel dielectrics rods of circular cross section, whose intersections with a perpendicular plane form a triangular lattice is calculated.

Tight-binding description of the coupled defect modes in three-dimensional photonic crystals
TL;DR: The eigenmode splitting due to coupling of the evanescent defect modes in three-dimensional photonic crystals was well explained with a theory based on the classical wave analog of the tight-binding formalism in solid state physics.
