Effects on the focusing of 3D elliptical reflector with strong chiral background supporting both PPV and NPV modes

The reflected electromagnetic waves from a perfect electric conductor (PEC) 3D elliptical reflector with chiral background with high value of chirality parameter kβ are discussed. The chiral medium supports both negative phase velocity (NPV) and positive phase velocity (PPV) simultaneously by increasing the concentration of chiral objects in the host medium, i.e., with strong chiral medium. For the value of −1 < kβ < 1 only PPV can propagate in the chiral medium with 3D elliptical reflector and out of this range both PPV and NPV are supported by the chiral medium with 3D elliptical reflector embedded in chiral medium. The derived high frequency field expressions with the help of geometrical optics (GO) and Maslov's method are simulated using MATLAB software with different values of chirality parameter kβ greater than one.
