Abstract

Non-linear propagation of finite-amplitude ion-cyclotron waves, ion-acoustic waves and solitary waves in a collisionless magnetized plasma, consisting of warm ions and isothermal electrons, is theoretically studied. New analytical solutions have been obtained for the excitation of these waves in the plasma. The nature of solutions for these waves are represented graphically. It is seen that the normalized electric field can have arbitrary small as well as large values for the existence of ion-cyclotron waves which contradicts the results of other authors.

Keywords

collisionless magnetized plasma; ion-cyclotron waves; ion-acoustic waves; solitary waves; non-linear propagation; analytical solutions waves
