Comments to deducing the formulas for gaussian quasiphotons by the complex space-times ray methods (STRM)
V. M. Babich St. Petersburg Department of Steklov Mathematical Institute of Russian Academy of Sciences
Abstract:
Quasiphotons-asymptotic solutions of wave equation with gaussian concentration around moving along rays points – are considered. It is stated in this note, that well-known procedures of obtaining the formulas for quasiphotons lead to complete class of quasiphotons, described by complex space-time ray method (STRM), in spite of very restrictive normalizing condition. It is possible, in the case of the constant velocity, to deduce formulas in explicit form for $3\times3$-matrices, describing quasiphotons. (This matrices in particular can have all nonzero components).
Key words and phrases:
quasiphoton, space-time ray method.
