A magnetostatic forward volume wave directional coupler with a guiding slot structure
A magnetostatic forward volume wave (MSFVW) directional coupler with a slotline structure is discussed. The structure consists of a slotted metallic layer deposited on a YIG film. The propagation of MSFVWs along the structure has been confirmed experimentally except around the lower limit of the MSFVW band. In addition, a description is given of a directional coupler with adjacent guiding slots fabricated on an epitaxial yttrium iron garnet (YIG) grown on a gadolinium gallium garnet (GGG) substate. A nearly 100% power transfer from one slotline to the other has been demonstrated. The directivity was measured to be above 20 dB except around the lower frequency limit.<>
