ELECTROMAGNETIC-FIELDS IN AN INHOMOGENEOUS-PLASMA FROM OBLIQUELY INCIDENT TRANSIENT PLANE-WAVES

In this paper, transient fields inside gyrotropic media are studied by a time domain Green function technique based upon a wave-splitting me thod. The medium is stratified in one spatial direction and the incide nt field is a plane electromagnetic pulse of arbitrary waveform at obl ique incidence. Green operators are introduced which map the incident field to the internal fields. The relation between the Green operators and the scattering operators used in the invariant imbedding method a re discussed. By introducing a complementary medium, a reciprocity rel ation is derived from which useful relations for the Green operators a re obtained.
