Theory of characteristic modes for conducting bodies
A theory of characteristic modes for conducting bodies is developed starting from the operator formulation for the current. The mode currents form a weighted orthogonal set over the conductor…

A surface formulation for characteristic modes of material bodies
A theory of characteristic modes for material bodies is developed using equivalent surface currents. This is in contrast to the alternative approach using induced volume currents. The mode currents…

Matrix methods for field problems
A unified treatment of matrix methods useful for field problems is given. The basic mathematical concept is the method of moments, by which the functional equations of field theory are reduced to…

Characteristic modes for dielectric and magnetic bodies
A theory of characteristic modes for material bodies, both with and without losses, is developed. For loss-free bodies, the modes consist of a set of real characteristic sources which diagonalize the…

Effect of antenna size on gain, bandwidth, and efficiency
TLDR
It is found that the maximum gain obtainable from a broad-band antenna is approxima tely equal t o that of the uniformly Illuminated aperture, and if higher gain is desired, the antenna mus t necessarily be a narrow-band device.

Reactively controlled directive arrays
TLDR
The radiation characteristics of an N -port antenna system can be controlled by impedance loading the ports and feeding only one or several of the ports, and the direction of maximum gain can becontrolled by varying the load reactances.
