Abstract

A metal slit array in a tapered parallel plate waveguide (TPPWG) is experimentally and numerically demonstrated. The metal slit array is embedded in the center of air gaps in tapered regions, realizing multiple narrow Bragg resonances. TPPWG not only enhances the Bragg resonances but also reduces the number of non-Bragg resonances. By adjusting the slit width, the frequency of Bragg resonances can be manipulated. The induced standing waves at 0.3, 0.5 and 0.7 THz exhibit enhanced localized field with multiple antinodes, which originates from the interference between two THz waves divided by the metal slit array.
