The Chu fundamental limitation on Q for electrically small antennas is well known and widely used. However, Chu did not include energy stored inside the hypothetical enveloping sphere. Exactâ€¦ (More)

In some recent publications, King (1990, 1992) and King and Sandler (1994) have provided formulas for the electromagnetic field radiated by an infinitesimal vertical Hertzian dipole above a lossyâ€¦ (More)

We present an exact analytical solution for the radiation impedance of an infinitesimal dipole surrounded by a thin spherical shell of epsilon negative material (ENG). The negative epsilon leads to aâ€¦ (More)

Two particularly accurate solutions representing the scatter of a Gaussian laser beam from a perfectly conducting cylinder, one a physical optics solution using a series Green's function and theâ€¦ (More)

The solution of a problem involving the scattering of an incident electromagnetic field by an obstacle is easily solved when the obstacle has a boundary corresponding to a constant coordinate surfaceâ€¦ (More)
