Abstract:
1. An electrical resonator system comprising: a plurality of concentric electrical resonator shells, wherein the plurality includes a first group of shells and a second group of shells, each shell including a substrate having first and second surfaces and a close-packed arrangement of electrically conductive material formed on the first surface of each shell and configured to operate at a desired passband of electromagnetic radiation, wherein for the first group of shells the close-packed arrangement comprises a first plurality of electrical resonators haying self-similar shapes, and wherein for the second group of shells the close-packed arrangement includes a second plurality of electrical resonators having self-similar shapes, and wherein a size change is implemented between the first plurality of electrical resonators of the first group of shells and the second of electrical resonators of the second group of shells; wherein a resonator shape in the close-packed arrangement of the first or second groups of shells comprises a second order or higher fractal.
