Ion‐implanted magnetostatic wave reflective array filters

摘要

Ion‐implanted bars have been used in fabricating magnetostatic surface wave normal incidence reflective array filters at 3.0 GHz. A theory is presented, based on a dispersion relation derived from a four layer model, and data taken agrees well with the theory. The ion‐implanted bars provide a solution to problems previously associated with etched grooves and metal bars.
