Abstract :
A spherical antenna is covered by a finite layer of lossy hot plasma. The radiation of this antenna is quite different from that of the same antenna imbedded in an infinite plasma. The antenna radiation can be recovered or enhanced when the plasma frequency is increased beyond the antenna frequency. An electro-acoustic wave may be excited in the plasma layer and leads to some resonance. The electroacoustic resonances may lead to a very strong antenna radiation. A good agreement was obtained between theory and experiment.
