as a very compact and lightweight transverse waveguide filter element.
A narrow-band transmission response is produced from two
layers, which, otherwise, in isolation would exhibit a broadband
response. Measured results are compared with theoretical data obtained
from a Transmission Line Matrix (TLM) based modeling
method. Reduction in the passband bandwidth of a factor of four
has been achieved using the proposed structure.
