| Popis: | Based on a differential equation derived analytically in terms of wakefield potential ϕ MW in a plasma filled rectangular waveguide, we investigate the wakefield ( E MW ) generated with the help of Gaussian-like microwave pulse under the effect of microwave frequency ( f ), pulse duration ( τ ), waveguide width ( b ), equilibrium plasma density ( n 0 ) and microwave intensity ( I ). The study conducted for three cases of τ > 1/ f p , τ = 1/ f p and τ f p , where f p is the plasma frequency, reveals that the amplitude of the wakefield is increased for the large pulse duration and higher microwave intensity but is decreased with the waveguide width and microwave frequency for all these cases. The wakefield shows stronger dependence on the microwave frequency when the microwave with larger intensity is used. The wakefield decreases at a faster rate with the waveguide width for the case of τ > 1/ f p . |
