https://doi.org/10.1007/978-3-642-28096-2The phenomenon of “cross-over” is important in the theory of ion cyclotron whistlers observed in satellites (Barrington et al 1966). It is studied here for radio waves vertically incident on the ionosphere, when the earth’s magnetic field is nearly vertical, and when the wave frequency is less than the gyrofrequency for protons.

The Coalescence of Coupling Points and “Cross-Over” for Ion Cyclotron WhistlersThe phenomenon of “cross-over” is important in the theory of ion cyclotron whistlers observed in satellites (Barrington et al 1966). It is studied here for radio waves vertically incident on the ionosphere, when the earth’s magnetic field is nearly vertical, and when the wave frequency is less than the gyrofrequency for protons.

A Numerical Method for the Integration of the Equations Governing the Propagation of E.M. Waves in aThe behaviour of the horizontal components of the fields of E.M. waves in an horizontally stratified magneto- ionic medium depends on the Clemmow and Heading (C.H.) vectorial equation †† . where . in a four dimensional basis system and where T is the propagation matrix.
