It is proved that consideration for the retardation effects at distances comparable with the characteristic dimensions of inclusion not only changes formulas for constitutive parameters but also enhances the role played by the Drude transition layer in calculation of the reflection coefficient describing It allows to model the transmission and reflection of electromagnetic waves in dependence on the obtained parameters of artificial helicoidal medium and to design the device for polarization transformation. Reflection and Transmission Coefficients. In Lecture 19 we derived the relation between the amplitudes of reflected and transmitted waves Further developed by Fresnel and Kirchhoff Destructive interference except in the forward direction. If we examine the Fresnel transmission coefficients ts and tp at total reflection, we notice that ts and tp are not vanishing. This means that even though the light energies are totally reflected, the electromagnetic fields still penetrate into the second medium. Evanescent Waves The electric field to the transmission and reflection of electromagnetic waves. on a planar surface between two non- magnetic media.For loss-less (and approximately also for low-loss) media, the Fresnel reflection coefficients are real. A plane electromagnetic wave propagating through free space is incident at an angle upon an infinite dielectric medium. This model computes the reflection and transmission coefficients and compares the results to the Fresnel equations. Let the electric field vector of a plane-wave component of a propagating electromagnetic wavefront be of the form.Figure 11: Absolute value of the Fresnel reflection coefficients for the pc- wave, both for s- and p-polarization, as a function of the angle of incidence i .
