Abstract

It is shown here that the usual operating frequencies for RF limiters, in the nominal 5, 11 or 15 GHz center frequencies, can be lifted up into the much higher frequencies of the 40 to 60 GHz range by a new formula developed from fundamental spin wave electromagnetic interactions in magnetic material characterized by a magnetization M.
