TRANSIENTS IN MAGNETO-IONIC MEDIA AND INTERRELATIONS BETWEEN ORDINARY AND EXTRAORDINARY HAVE REPRESENTATIONS

摘要

For a time harmonic case, ordinary and extraordinary waves are independent modes in magento-ionic media. However, for a transient, an inverse Laplace transform of the time harmonic solution of each mode does not yield a real function of time, and a special care, which is unnecessary for isotropic media, must be taken for magneto-ionic media. This paper discusses this aspect of- the transient and shows a general form of the representations of the transient which clarifies the interrelations between ordinary and extraordinary wave representation.
