Abstract :
A Bessel resonator for producing Bessel-type modes at THz has been designed and analyzed in our paper. The resonator is designed according to quasi-optical theory. To analyze the designed resonator rigorously, we have developed a new iterative method from the classical Fox-Li algorithm. Using this method, the resonating modes of the designed resonator at THz are calculated. Analysis results are presented in this paper.
