Abstract :
Transform techniques are applied to obtain a solution describing the characteristics of electromagnetic waves propagating in media which are subject to abrupt time changes in permittivity. The case of a spherically expanding wave is considered in detail. The plane wave case is also discussed. Transform techniques provide a mechanism for easily extending the solutions through successive time changes.
