A slab metamaterial lens with a refractive index of −1 is capable of producing a perfect image, since it transfers all the plane waves from the object plane to the image plane without creating any distortion in their ...

In physical optics prediction of radar cross section, the surface of the object is usually modeled by flat triangular meshes in order to simplify the intersection test and electromag- netic field calculations. This geometrical ...

This paper present a new technique for determination

of illuminated region in the shooting and bouncing ray

(SBR) method. The ray tracing part of SBR method consumes

the most of computational resources ...
