| Abstract: | On the bases of WKB approximate method solution of electromagnetic wave equation the characteristics of the rocket wake flame interference are calculated and analyzed. The electromagnetic interference of the rocket wake flame electromagnetic parameters including plasma frequency,electron collision frequency and electron density are calculated and analyzed. The results show that the attenuation of the electromagnetic signals are decided by both of the frequency of the electromagnetic wave and the electromagn... |
