Whistler wave propagation in magnetospheric ducts (in the equatorial region)

摘要: Abstract An analytical theory of whistler wave propagation in axially symmetric field-aligned density ducts is developed. Both enhancements and rarefactions the (crests troughs) are considered. Simple equations giving dependence number modes n upon angular frequency ω derived. From these results it follows that crests decreases when approaches c 2 for . The limiting trapping calculated. investigation attenuation a crest due to leakage presented. analysis troughs , > → shows same order magnitude three cases.
