Abstract

Nonreciprocal magnetostatic wave propagation in micro-patterned Ni₈₀Fe₂₀ thin film has been investigated. The nonreciprocal devices consist of a set of coupled microstrip transmission lines acting as antennae on the top of the micro-patterned Ni₈₀Fe₂₀ films. The Ni₈₀Fe₂₀ films were structured into an array of rectangular prisms. Nonreciprocal wave propagation was observed in the patterned Ni₈₀Fe₂₀ film. Compared to the control device with a continuous Ni₈₀Fe₂₀ film, the micro-patterned Ni₈₀Fe₂₀ films led to a weaker non-reciprocity.
