Accelerator applications of engineered media

Material properties are vital for the field of accelerator R{\&}D. Euclid Techlabs in collaboration with the Argonne Wakefield Accelerator facility team has investigated accelerator applications of metamaterials, photonic band gap structures, nonlinear, paramagnetic and ferroelectric materials. In this paper we will present results of our work on advanced accelerating structures and accelerating applications of engineered materials. These will include wakefield test of a photonic band gap accelerating structure, design of a dielectric loaded structure with built in tunable paramagnetic absorption mechanism and beam diagnostics applications of metamaterials.
