Abstract

The transmission and reflection performance of multiple thick diaphragms inside a rectangular waveguide is vastly different from a single diaphragm of comparable size due to the conducted EMI between the diaphragms. The characterisation of such a structure is carried out by full wave analysis with the help of method of moments. It is shown that diaphragms separated longitudinally by dielectric material can behave as a RF switch. The theoretical finding is compared with experimental measurements. Means of shifting the switching frequency of the switch is also indicated.
