TLDR
It is demonstrated that lattice imperfections in a periodic array of dielectric material can give rise to fully localized electromagnetic states that are tunable by varying the size of the defect.Abstract:
It is demonstrated that lattice imperfections in a periodic array of dielectric material can give rise to fully localized electromagnetic states. Calculations are performed by using a plane-wave expansion to solve Maxwell's equations. The frequency of these localized states is tunable by varying the size of the defect. Potential device applications in the microwave and millimeter wave regime are proposed.read more

Photonic crystals: putting a new twist on light
TL;DR: In this article, the authors describe the photonic bandgap as a periodicity in dielectric constant, which can create a range of 'forbidden' frequencies called a photonic Bandgap.

A uniplanar compact photonic-bandgap (UC-PBG) structure and its applications for microwave circuit
TL;DR: In this article, the photonic bandgap (PBG) structure for microwave integrated circuits is presented, which is a two-dimensional square lattice with each element consisting of a metal pad and four connecting branches.

Photonic band gaps in three dimensions: New layer-by-layer periodic structures
TL;DR: In this article, a 3D periodic dielectric structure with circular, elliptical, or rectangular shape is introduced. But the 3D layer structure can be easily fabricated using conventional microfabrication techniques on the scale of optical wavelengths.

Existence of a photonic band gap in two dimensions
TL;DR: In this paper, a two-dimensional periodic dielectric structure that has a complete inplane photonic band gap for both polarizations was identified, and a triangular lattice of air columns was found to have the desired band gap properties.
