Abstract
Frequency tunable millimeter wave filters are considered to be fabrica ted using metallic ferromagnetic thin films. Whereas conventional filt ers which include insulating ferrite materials utilize the phenomenon of ferromagnetic resonance (FMR), our design incorporates the phenomen on of ferromagnetic anti-resonance (FMAR). Our calculations indicate t hat in comparing the characteristics of the two types of filters the f ilter utilizing magnetic metal films is superior in terms of insertion loss and integrability with other planar millimeter wave devices. Des ign of band-pass filter can be realized in which the transmission freq uency occurs at FMAR frequency with a frequency bandwidth equal to the FMAR linewidth.
