Abstract
Based on the mode-coupling method, numerical simulations comparative study are carried out to study the frequency response characteristics of the coaxial Bragg structure with different windowing functions on coupling modes. Results show that when employing the windowing-function techniques, the residual side-lobes of the frequency response can be effectively suppressed. When employing the Bragg structure with Blackman windowing function, its reflectivity of the working mode and the competing mode is the minimum. When employing the Bragg hamming windowing function, its reflectivity of the working mode and the competing mode is the maximum. These characteristics can improve its performance when the Bragg structure is used as a reflector or filter.
