Changes in transmission spectrum, losses and reflection of electromagnetic waves by radar thin film of metallic silver nanoparticles

In this paper، reflection and transmission absorption spectrum of the nanocomposite thin silver film on the outer surface of the submarines، ships، aircraft، etc. deposition has been measured. So that they can be out of sight of other radars. with considering that most radar behave at bands x and k. then it has studied on the band x. to obtain the coefficients of absorption، reflection and transmission of vertical and oblique، the coefficient of Maxwell''s equations and Snell-Descartes also used. the case of a monochromatic wave with polarization perpendicular or wish to make clear that the thin films such as blade is radiated. then the successive reflections، and can absorption coefficients، passing and reflection were calculated. and the coefficients of variation of the angle of incidence، the frequency of the electromagnetic wave and the input parameters and draw a thin film thickness. and discussion of the results and the optimum conditions for various applications and present recommendations. following conclusions done.
