A note on radiation in a gyro-electric-magnetic medium--An extension of bunkin´s calculation

Some fundamental results on radiation in anisotropic media have been worked out by F. V. Bunkin for the case of a gyro-electric (or plasma) medium using the technique of tensorial Green´s function. He obtained asymptotic expressions for the far-zone radiation fields in a gyro-electric medium and therefore demonstrated actually the validity of Sommerfield´s radiation condition for a gyro-electric medium. The present paper extends Bunkin s calculation to a case of a gyro-electric-magnetic medium and thus justifies the validity of Sommerfeld´s radiation condition in a gyro-electric-magnetic medium.
