Abstract
A thin film magnetodielectric (TFM) structure is disclosed which has effective absorption with minimal reflection of electromagnetic radiation over a broad band of frequencies. The thin film magnetodielectric structure has an effective electric susceptibility and effective magnetic susceptibility which are substantially equal for a broad band of electromagnetic wavelengths. The disclosed TFM structure includes layers of thin film magnetic elements which are surrounded by and supported in a dielectric medium. Each thin film element is preferably rectangular in shape and has a thickness substantially less than the long and short axes of the element. Each layer includes a plurality of elements arranged in an orderly array with the long axes of each element in a layer substantially parallel to each other. Either neighboring layers or neighboring stacks of layers have elements whose long axes are oriented at 90°.
