Abstract
The use of two-dimensional (2D) Bragg resonators of coaxial geometry, realising: two-dimensional distributed feedback. is considered as a method of providing additional mode selection and producing spatially coherent radiation from oversized annular electron beams. The main goals of the project are to prove operability of a FEM using 2D Bragg structures and compare the performance of the FEM using the novel 2D Bragg! resonators with conventional 1D Bragg resonators.
