Abstract
We discuss recent progress in our effort to develop a high gradient accelerator cavity based on Photonic Band Gap (PBG) concepts. Our proposed cavity consists of a two-dimensional (2-D) photonic lattice, composed of either dielectric or metal scatterers, bounded in the third dimension by flat conducting (or superconducting) plates. A defect introduced to the lattice, usually a removed scatterer, produces a defect mode with fields concentrated at the defect site and decaying exponentially in all directions away from the defect site. The defect mode is designed to resonate at frequencies in the 2–20 GHz range, where metals can still be used to confine the energy with minimal loss. We present in this paper some of the technical considerations which have arisen relevent to this application, and to PBG structures in general. In particular, we focus on measurements and calculations carried out for a 2-D metal PBG cavity.
