A critical review is presented of recent progress in classical diffraction theory. Both scalar
and electromagnetic problems are discussed. The report may serve as an introduction to …

A new method is developed for expanding the electromagnetic field of radiating charges
and currents in multipole components. Outside a sphere enclosing all sources, the field is …

According to La Paz and Miller the theoretical optimum current distribution on a vertical
antenna of given length is defined as that current distribution giving the maximum possible field …

This paper treats of the effect of space differenitation upon wave functions, describing the
diffraction by infinitely thin plane screens. As already indicated by Lord Rayleigh, certain …

The field of radiation produced by a harmonically oscillating membrane with arbitrary amplitude
distribution in a closely fitting aperture of an infinite rigid plane is studied. The analysis …

Es wird theoretisch untersucht, wie die Einstellzeit der Spins in paramagnetischen Kristallen
in Anwesenheit eines~. usseren Magnetfeldes yon dessert StArke abh/ingt, wenn das …

Es werden die Energieniveaus der Spins im Eisen-Ammoniumalaun unter gleichzeitiger
Einwirkung eines elektrischen Kristallfeldes kubischer Symmetrie und eines konstanten …

In this paper the field of a point charge inside a hollow, infinitely long circular cylinder is
studied. The case of an axial point charge is treated in detail. Three different methods are …

NUMEROUS papers on the theory of propagation of electro-magnetic waves over plane
earth have appeared, following Sommerfeld's celebrated paper'of 1909. Though it has been …
