Modeling of a Waveguide Stop-band Filter with a Mushroom-shaped Metamaterial Wall and Dielectric Substrates

The scientific paper is dedicated to the investigation of a rectangular waveguide R32 type with magnetic wall of mushroom-shaped metamaterial supplemented by a dielectric substrate. The computer model of the waveguide filter under consideration and its quantitative characteristics of S-parameters and voltage standing wave ratio received are presented. All collected data are appropriately organized in terms of convenience to compare the figures and submitted as the frequency dependence plots which are more representative and straightforward for analysis. Based on the results obtained it is possible to make assumptions about the qualitative transformation of waveguide properties under the influence of a mushroom-shaped metamaterial and prospects for a future integration this construction in the microwave devices. This groundbreaking treatment could be an underlying solution to the problem of miniaturization and performance in the modern technology development.
