Paper Abstract

A few reasons to cause the half-wave hole for the short-wave pass filter had been analyzed. According to these reasons, the application of a new admittance-matching method and a photoelectric maximum control with half-wavelength effectively eliminated the half-wave hole. The matching stack consisted of a symmetrically periodic structure and provided a complete matching at the desired wavelength; i.e., both conditions for the equivalent admittance and phase thickness were fulfilled. Furthermore, both the theoretical and the tested curves had been given, and a good agreement between them was obtained.
