The effects of width modes in magnetostatic forward volume wave propagation
Abstract
Delay line amplitude ripple and out-of-band filter response in magnetostatic forward volume devices are shown to be due to the transduction and propagation of width modes, which at low wavenumbers have different phase and group velocities, but at high wavenumbers become degenerate. Various techniques which minimize the effects of width modes are suggested and results obtained on the preferential attenuation of higher order width modes by thin resistive strips are described.
