ABSTRACT
The physics of the interaction of electromagnetic (EM) waves with plasmas has been an active area of research over the years [1-12]. In the presence of a static magnetic field in the plasma, the interaction becomes all the more interesting due to the generation of a variety of wave modes, cutoffs, and resonances [1]. Most of the earlier experiments have focused on launching waves parallel to a nearly uniform axial magnetostatic (Bo) field produced by current-carrying coils (k ‖ Bo case) [1-5]. The experiments on the Whistler [2,3] and the electron-cyclotron waves are well known [4,5]. A few investigations, where waves are launched perpendicular to the static magnetic field (k ⊥ Bo case), have also been carried out by Sugai [6], Rypdal et al. [7], and Yadav and Bora [8], with emphasis on wave interactions in the UHR region.
