Paper Abstract

Metamaterials have negative refractive index and EM waves bend negatively. This negative bending allows a variety of applications from microwaves to optical frequencies. Negative refraction can be exploited to make novel lenses having flat surfaces and focus electromagnetic waves as well as produce a real 3-D image. These flat lenses do not have unique optical axes and the aperture sizes are smaller than a square wavelength. The electromagnetic field propagation on a multilayer structure: normal-metamaterial-normal is investigated and compared with homogenous media. The numerical method, FDTD, was used for a Gaussian source and for more sinusoidal sources. The point focusing analysis of a flat lens is presented.
