Characteristic modes for dielectric and magnetic bodies

A Novel Approach to Beam Steering Using Arrays Composed of Multiple Unique Radiating Modes

“…The theory of characteristic modes uses an eigenmode expansion to derive the supported real current modes on conducting and dielectric bodies of arbitrary shape [18,19]. This method not only provides physical insight into the behavior of the antenna but also allows antenna geometries to be synthesized from a set of desired radiation pattern properties [20].…”

Computer Programs for EMC Based on the Methods of Moments.

“…Program descriptions and listings are included in the corresponding research report [142]. A theory of characteristic modes based on a volume current formulation rather than on equivalent surface currents was presented earlier [143]. An early treatment of material bodies using the equivalent surface current approach was performed by Harrington and his coworkers as one of the original tasks performed [107].…”

Design Guidelines for the Excitation of Characteristic Modes in Slotted Planar Structures

“…HE Theory of Characteristic Modes (TCM) [1][2] has demonstrated to be really helpful for the analysis and design of different types of antennas, such as small antennas [3][4], wire antennas [5] [6], planar patches and monopoles [7][8], vehicle mounted antennas [9][10], handset antennas [11]- [13], or dielectric antennas [14] insight they provide of the resonances and radiating behavior of arbitrarily shaped metallic bodies. In the last years, the number of publications concerning the application of this modal theory to the design of antennas has increased exponentially.…”
