Waveguide termination with a magnetic wall on the mushroom-shaped metamaterial modeling

Waveguide termination modeling with a mushroom-shaped wall were carried out. Voltage standing-wave ratio (VSWR) and reflection coefficient (S11) frequency dependencies were obtained. High values of the mushroom-shaped structure unloaded quality factor are the main advantage of explored design. The using of distributed LC-resonant circuit with dimensions which significantly smaller than wavelength allows creating a compact termination working in microwave range.
