Expressions are derived for the smallest achievable radiation quality factor ( ) of an electrically small antenna in front of a conducting plane. Applying the low-frequency approximation to theâ€¦ (More)

8 9 Digital elevation models (DEMs) are widely used in the modeling of surface hydrology, which 10 typically includes the determination of flow directions and flow accumulation. The use of high11â€¦ (More)

A transformation linking spherical multipole fields with generalized spheroidal multipole fields is derived. Applications including the inverse diffraction problem for spherically-scanned near fieldâ€¦ (More)

INTRODUCTION Recently, we have investigated the classical inverse source problem of reconstructing an unknown radiating source from knowledge of the exterior field it generates, with emphasis onâ€¦ (More)

The elementary split ring resonator is a key structure in so-called “metamaterial” mediums. In this presentation, low-frequency electromagnetic scattering by a split ring, modelled as aâ€¦ (More)

The magnetic energy and inductance of current distributions on the surface of a torus are considered. Specifically, we investigate the influence of the aspect ratio of the torus, and of the pitchâ€¦ (More)
