| Abstract: | Comparative study of the multi-mode theory with the Computer Simulation Technolgy(CST) software is carried out for the numerical simulations of a new coaxial Bragg reflector corrugated with sinusoidal ripples.Results show good agreement between the multi-mode theory and the CST software.However,compared with the CST software,the multi-mode theory has the peculiarities of easy programming,fast calculation speed,and convenient adjusting,and the bandwidth of the coaxial Bragg reflector with positive taper can ... |
