The electromagnetic time-reversal (TR) technique has the characteristics of spatiotemporal focusing in a cavity (TRC), which can be used for pulse compression, thus forming an with high peak power. A time-reversed pulse-compression method single channel compression gain. However, only generate limited This paper proposes novel TR power-combination multichannel TRC to obtain higher power based o...

in this study, a new efficient semi-analytical method is introduced to give approximate solutions of strongly nonlinear oscillators. the proposed method is based on combination of two different methods, the multi-step homotopy analysis method and spectral method, called the multi-step spectral homotopy analysis method (msham). in this method, firstly, we propose a new spectral homotopy analysis...
