A MAGNETOELASTIC TWO-PORT CONFIGURATION IN YIG

Abstract
Two‐port magnetoelastic delay performance has been obtained at 1300 MHz in an axially magnetized, [100] oriented YIG rod by injecting longitudinal elastic waves along a [001] axis near the rod end. The polished rod end‐face, beveled 28.1° with respect to the rod axis, converts this elastic beam into a linearly polarized shear wave column which propagates down the rod axis. One circularly polarized component of this wave undergoes conventional magnetoelastic conversion and detection to provide the second port.
