Abstract :
The yttrium iron garnet (YIG) film microstrip line was fabricated by using 40-μm-thick film with a width of 20 mm and a length of 10 mm along with a 0.7-mm-wide microstrip and was magnetized in a transverse direction to the wave propagation. Sharp notch characteristics of more than 30 dB with few dB insertion loss were observed experimentally with a variable center frequency from 9 GHz to 11 GHz. Results are explained phenomenologically with the coupled mode theory
