This paper proposed a semi-analytical solution for evaluation of field distributions around the surface of a ferromagnetic metallic half space, which contains a hidden long crack and excited by a three-dimensional arbitrary frequency current-carrying inducer. The solution was obtained by using the method of separation of variables in three dimensions. This research assumed that the conductor as a lossy dielectric and used the concept of a rectangular waveguide, which is partially loaded with die...

Abstract A 20 dB Bethe Hole coupler is designed and fabricated using ridge gap waveguide technology for operation at the Ku band. The use of ridge gap waveguide concept makes an opportunity to develop a lowloss and wideband directional coupler because of supporting TEM wave propagation in air region.The simulation results show a very flat -20dB coupling coefficient response, higher than 20dB isolationand proper impedance matching over a wide frequency rangewhich are in agreement with the measure...
