Photonic crystal waveguides for particle acceleration

In this work we design and numerically study an all-dielectric accelerating waveguide operating at radiofrequency, and we describe the structure of the input coupler which is necessary to efficiently excite the accelerating mode. We then study single-particle dynamics in the proposed accelerator, by estimating the performance of the resulting device through the evaluation of the key parameters that are typically used to characterize traveling-wave accelerators.
