Study of the magnetic tuning effect in HTS coplanar resonators

Abstract

Formulae for calculating the resonance frequency and the microwave (MW) losses in HTS thin film coplanar waveguide resonators containing a tangentially magnetized ferrite layer were obtained using the perturbation method. The problem of achievement of a maximum sensitivity of the resonance frequency to the field intensity and the problem of reducing the MW losses contributed to the resonator by the magnetostatic waves were analysed.
