Abstract:
1. An apparatus comprising: a dielectric structure configured for placement in a waveguide; and a plurality of conductive segments located within the dielectric structure along an axis shared by each of the plurality of conductive segments, wherein each of the plurality of conductive segments is configured to reduce a passing of a number of frequencies of electromagnetic signals traveling through the dielectric structure, wherein the plurality of conductive segments include at least a first conductive ring and a second conductive ring, wherein the first conductive ring has a first pair of gaps located opposite each other on the first conductive ring, wherein the second conductive ring has a second pair of gaps located opposite each other on the second conductive ring, and wherein the first pair of gaps are rotated about ninety degrees with respect to the second pair of gaps relative to the axis.
