Abstract :
The influence of waveguide spacing on transmission response for parallel-plate waveguide with a single deep cavity has been experimentally studied. The results indicate the depth of cavity determines the maximum channel number and the channel number control can be achieved by changing the waveguide spacing. Results show that this structure can be used to be a promising tunable number-adjustable terahertz notch filter.
