TE10 transmission enhancement for X-band guided waves using multi-mode metamaterial array and multi-mode extractor-converter structures

In this paper, guided waves with enhancement TE₁₀ transmission using multi-mode metamaterial array and multimode extractor-converter structures have been introduced and analyzed using the full 3D electromagnetic field inside a structure based on the finite element method. The proposed structure presents TE₁₀ enhancement transmission coefficient ratio up to 35.3 through different varieties of metamaterial array, mode extractor-converter structures and combined together compared to the conventional guided waves. The proposed structure characteristics such as metamaterial S-parameter retrieval results, the magnitude of electric field and transmission ratio for different cases are obtained to demonstrate the performance.
