Tapped microwave nondispersive magnetostatic delay lines

Abstract
Nondispersive magnetostatic surface wave delay lines when spatially tapped form the basis for real time signal processing at microwave frequencies. Devices have been fabricated reproduceably from narrow linewidth LPE‐YIG, spaced from a ground plane by a dielectric layer. Transduction and tapping of the magnetostatic waves was efficiently performed with fine line conductors at S‐band. Experimental performance and design limitations are discussed with particular emphasis on delay, transduction loss, propagation loss and power saturation.
