Abstract:
1. A structure comprising: a plurality of first elements disposed on a first plane of a device, each first element comprising a first metal layer, a dielectric layer, and a second metal layer, wherein each first element has a rectangular shape; a second element connecting each first element to an adjacent first element at a position on a side of the first element adjacent to a corner of the first element, the second element being disposed on the first plane of the device, the second element comprising a first metal layer, a dielectric layer, and a second metal layer, wherein the first elements and second elements substantially filter electromagnetic waves to a stopband floor of about −60 dB to about −120 dB in a bandgap of about 100 MHz to about 50 0Hz having a width selected from about 1 GHz, 2 GHz, 3 GHz, 5 GHz, 10 GHz, 20 GHz, and 30 GHz, and having a center frequency positioned at a frequency from about 1 GHz to 37 GHz; and wherein the plurality of first elements and second elements form a continuous, two-dimensional and periodic structure.
