Due to their excellent physical properties, former researches on Diamond-like carbon (DLC) and Porous silicon (PS) structures showed good results in the field of photovoltaic devices. In the last two decades, many researchers have reported the exceptional properties of newly synthesized materials that are not found in nature. Those materials are termed as Left-Landed Materials (LHMs). The aim of this thesis is to study transmitted, reflected and loss powers of a multilayer structure composed of LHM, PS and DLC placed in vacuum when transverse electric plane waves are incident on it. The electromagnetic transmitted, reflected and loss powers as a functions of the incident frequency have been computed numerically and plotted using MATLAB software. In this thesis, theoretical and analytical investigations of electromagnetic wave propagation through the proposed structure are achieved. A transverse electric polarized plane waves are normally and obliquely incident upon the proposed structure. The reflected, transmitted and loss powers of structure have been studied. For left-handed material, two cases, the loss-less and loss case are considered. In our calculations, we apply the transfer matrix approach. In order to calculate the reflected, transmitted and loss powers, reflection and transmission coefficients have been formulated. In computations, the effect of changing the values of dissipation factor, thicknesses of slabs and angles of incidence has been studied. In this work, the results show an excellent results for high transmission of the incident waves for certain frequency bands. Hence, the studied structure would be promising to be utilized in the field of solar cells.
