Experimental Verification of Mode Coupling Phenomenon in High Permittivity NRD Guide with Small Remaining Asymmetrically Air Gap

摘要

It is known that a high permittivity NRD guide suffers from irregular transmission phenomena. In this study, we clarified that this problem is caused by a mode coupling phenomenon between the operating and parasitic modes due to a small remaining asymmetrically air gap between the metal plates and high permittivity dielectric materials.
