An explicit proof of the completeness of the eigenmodes of a grounded parallel plate waveguide with a perfectly matched layer termination is given. The proof is based on a general theorem governing the completeness of sets of complex exponentials. The Greens It is suggested to use a basis of discontinuous solutions of the wave equation (the generalized Sommerfeld solution) to describe scattering effects by a thin half-plane. This makes it possible to construct the self-consistent wave spectrum of a semiinfinite plate

** Waveguide Termination with a Magnetic Wall on the Mushroom-Shaped Metamaterial Modeling**

Waveguide termination modeling with a mushroom-shaped wall were carried out. Voltage standingwave ratio (VSWR) and reflection coefficient (S11) frequency dependencies were obtained. High values of the mushroomshaped structure unloaded quality factor are the

Abstract- We present the design, fabrication, and characterization of a novel matched waveguide termination based on planar artificial metamaterial. This matched termination is realized by recent developed planar metamaterial absorber, which can be designed to near
