	Funding: Work supported by US DOE, High Energy Physics, Grant DE-SC0010075 An overmoded hybrid Photonic Band Gap (PBG) structure used as an accelerator cavity has been theoretically designed. The PBG structure consists of a triangular lattice of dielectric (sapphire) and metallic rods. The birefringence of the sapphire affects the PBG eigenmodes and must be taken into account. The PBG cavity formed by rods in between two copper plates will be operated in a TM02 mode at 17 GHz. Arrangement of the rods for higher-order-mode (HOM) damping demonstrates high frequency selectivity. Comparison with a disk-loaded waveguide (DLW) cavity gives a perspective of the dielectric PBG structure operated at an accelerating gradient of 100 MV/m. Cold test of a single hybrid PBG cell presents a high-Q resonance at 17 GHz. A standing-wave (SW) hybrid PBG structure will be tested in TM02 mode at 17 GHz.

An overmoded hybrid Photonic Band Gap (PBG) structure used as an accelerator cavity has been theoretically designed. The PBG structure consists of a triangular lattice of dielectric (sapphire) and metallic rods. The birefringence of the sapphire affects the PBG eigenmodes and must be taken into account. The PBG cavity formed by rods in between two copper plates will be operated in a TM02 mode at 17 GHz. Arrangement of the rods for higher-order-mode (HOM) damping demonstrates high frequency selectivity. Comparison with a disk-loaded waveguide (DLW) cavity gives a perspective of the dielectric PBG structure operated at an accelerating gradient of 100 MV/m. Cold test of a single hybrid PBG cell presents a high-Q resonance at 17 GHz. A standing-wave (SW) hybrid PBG structure will be tested in TM02 mode at 17 GHz.
