Paper Abstract

An overmoded photonic crystal waveguide based on the three-dimensional woodpile lattice has been proposed for a highenergy charged particle accelerator. Critical to overall accelerator efficiency is the ability to couple power into an uninterrupted vacuum waveguide in a very small volume. We present designs and simulations of coupling to the waveguide, both from free space and from a waveguide adjoining it at 90 degrees. We discuss details of the computation, including the use of symmetries and extraction of the resulting transmission.
