Abstract:
A thin film magnetodielectric structure comprising:a first plurality of thin film magnetic elements arranged in an orderly array in a first layer, wherein each of said thin film elements has major and minor axes in the plane of said layer and has a thickness which is substantially less than the lengths of said axes, and wherein the major axes of each of said elements in said first layer are substantially parallel to each other; a second plurality of thin film magnetic elements arranged in an orderly array in a second layer, wherein each of said thin film elements has major and minor axes in the plane of said layer and has a thickness which is substantially less than the lengths of said axes, and wherein said major axes of said elements of said second layer are substantially parallel to each other, and are oriented at an angle of 90Â° to the major axes of the elements of said first layer; and a dielectric medium surrounding and supporting said first and second layers of thin film magnetic elements; wherein said structure has effective magnetic and electric susceptibilities which are substantially equal over a broad range of frequencies of electromagnetic radiation incident upon said structure, whereby said structure absorbs with minimal reflection electromagnetic radiation over said broad range of frequencies.
