Los campos electromagnéticos se calculan para un cilindro finito, excitado por una fuente circular y, para propósitos de comparación, mediante excitación de una fuente lineal. Estos resultados también se comparan con los del caso del cilindro in

We review past research on the propagation of electromagnetic pulse signals over the surface of the earth with emphasis on analytical methods to predict waveforms. The best example is the electromagnetic field radiated from a lightning stroke that ca

A general Sommerfeld integral formulation is given for the electromagnetic (EM) fields of an oscillating vertical magnetic or electric dipole over an electrically inhomogeneous thin sheet. The electrical properties of the sheet are characterized by a

In 1977, Rosich and Wait (see Radio Science, vol.12, no.5, p.719-29, Sept./Oct. 1977) presented a general expression for a perturbation series solution to electromagnetic (EM) reflection from an imperfectly conducting periodic rough surface. This is

In this paper, we are interested in controlling the power dissipation within a homogeneous lossy cylinder of finite length when a field is applied to the surface of the cylinder. The fields are assumed to be independent of the azimuthal angle. To beg

Red sprites were discovered by chance in 1989 when a low-light TV system was pointed above an active thunderstorm. Optically, they are observed as clusters of short-lived (∼50 ms) pinkish-red luminous events, sometimes stretching from ∼40 to ∼8

Electromagnetic induction on a layered earth model is reexamined when the usually neglected magnetic permeability contrast is considered. It is shown that for a two-layered earth model, where the upper layer is permeable, the electromagnetic inductio

In an accompanying paper, Rodger et al. (1998) modelled a red sprite as a set of thin columns (‘spritelets’). By examining a semi-random distribution of coupled spritelets, they showed that the scattered field from a VLF radio transmitter has a c

A relatively simple model of Red Sprites as a set of conducting columns reproduces the radio physics properties of VLF sprites. The columnar structure of optical sprites is represented by thin vertical conducting columns (or ‘Spritelets’) in free

Expressions are developed to characterise the scattering of VLF electromagnetic waves from a finite-length ionised column at some height in the Earth–ionosphere waveguide. This formulation has been examined to investigate the perturbations of VLF t
