Photonic Band Gap Structures for Accelerator Applications

A photonic band gap (PBG) structure is a one-, two- or three-dimensional periodic metallic and/or dielectric system, which acts like a filter, reflecting rf fields in some frequency range and allowing rf fields at other frequencies to transmit through. PBG structures have many promising applications in active and passive devices at millimeter wave and higher frequencies. Metal PBG structures can be employed at X and Ku-band accelerators to suppress wakefields. Dielectric PBG structures are attractive at terahertz frequencies for construction of high gradient laser-driven accelerators. For both applications two-dimensional (2D) PBG structures are of main interest, although planar and three-dimensional (3D) structures are also used. In this paper a review of theoretical studies and computer modeling of 2D metal and dielectric structures is presented, and current experimental efforts on constructing and testing metal and dielectric PBG accelerators are discussed.
