Title :
On transient waves produced by a source on superluminal pulsate sphere
Author_Institution :
Inst. of Phys., St. Petersburg Univ., Russia
Abstract :
Transient, solutions of the inhomogeneous wave equation is constructed in terms of spherical harmonics. The source belongs to the spherical pulsating surface. The velocity of sphere is grater than the wavefront velocity. The possibility of description of electromagnetic waves by means of the scalar solution is discussed.
