Abstract :
Electromagnetic wave propagation in a rectangular waveguide for which both sides are exponentially tapered is discussed. The wave equation in the guide is a second-order nonlinear partial-differential equation which is solved numerically using the finite-element approach. The results obtained for large taper coefficients are useful in the design of miniaturized waveguide-microstrip transitions constituting the input and output sections of test jigs employed in solid-state circuits mounted in waveguide environments
