Constantine A. Balanis is a Greek-born American scientist, educator, author, and Regents Professor at Arizona State University. Born in Trikala, Greece on October 29, 1938. He is best known for his books in the fields of engineering electromagnetics and antenna theory. He emigrated to the United States in 1955, where he studied electrical ...
Selected uses in antenna theory include the analysis of aperture antennas [9] and the cavity model approach for microstrip patch antennas. [10] It has also been used as a domain decomposition method for method of moments analysis of complex antenna structures. [11] Schelkunoff's formulation is employed particularly for scattering problems. [2 ...

The thinned-array curse (sometimes, sparse-array curse) is a theorem in electromagnetic theory of antennas.It states that a transmitting antenna which is synthesized from a coherent phased array of smaller antenna apertures that are spaced apart will have a smaller minimum beam spot size, but the amount of power that is beamed into this main lobe is reduced by an exactly proportional amount ...
The antenna pattern is the response of the antenna to a plane wave incident from a given direction or the relative power density of the wave transmitted by the antenna in a given direction. For a reciprocal antenna, these two patterns are identical. A multitude of antenna pattern measurement techniques have been developed.
For such an antenna, the near field is the region within a radius r ≪ λ, while the far-field is the region for which r ≫ 2 λ. The transition zone is the region between r = λ and r = 2 λ . The length of the antenna, D, is not important, and the approximation is the same for all shorter antennas (sometimes idealized as so-called point ...
Note that the IEEE defines RHCP and LHCP the opposite as those used by physicists. The IEEE 1979 Antenna Standard will show RHCP on the South Pole of the Poincare Sphere. The IEEE defines RHCP using the right hand with thumb pointing in the direction of transmit, and the fingers showing the direction of rotation of the E field with time.
A 2006 report by a joint taskforce between the American Physical Society and the American Association of Physics Teachers found that 76 of the 80 physics departments surveyed require a first-year graduate course in John Jackson's Classical Electrodynamics. [4]
