In this paper, an analytic solution is presented using differential transform method (DTM) for a class of wave equation. The emphasis is on the nonlinear two-dimensional wave equation. The procedures introduced in this paper are in recursive forms which can be used to obtain the closed form of the solutions, if they are required. The method is tested on various examples, and the results reveal ...

We investigate the transmission coefficient for propagation of electromagnetic radiation, of frequency w, through an electron inversion layer, of finite thickness d, in the metal-oxide-semiconductor (MOS) structure. The corresponding result in the case where the inversion layer is treated as infinitely thin (two-dimensional electron gas) has been given by Chiu et al. Subject to the assumptions ...
