How to confine light energy associated with surface plasmon polaritons (SPPs) in a physical space with minimal radiation loss whereas creating maximum interacting section with surrounding environment is of particular interest in plasmonic optics. By virtue of transformation optics, we propose a design method of forming a polygonal surface-plasmonic resonator in fully open structures by applying...

The theory of measurement is employed to elucidate the physical basis of general relativity. For measurements involving phenomena with intrinsic length or time scales, such scales must in general be negligible compared to the (translational and rotational) scales characteristic of the motion of the observer. Thus general relativity is a consistent theory of coincidences so long as these involve...

Diffractive optical elements are components relying on the physical phenomena of diffraction and interference to control the propagation of light. Such elements are usually macroscopically planar microstructures, consisting of features with dimensions from a couple of wavelengths to a few tens of microns and being designed by advanced numerical algorithms based on rigorous diffraction theory. T...

We construct a numerical scheme based on the Liouville equation of geometric optics coupled with the Geometric Theory of Diffraction (GTD) to simulate the high frequency linear waves diffracted by a corner. While the reflection boundary conditions are used at the boundary, a diffraction condition, based on the GTD theory, is introduced at the vertex. These conditions are built into the numerica...

Coherent light exhibits properties that cannot be modeled by geometrical optics. Those properties include the limited focusability of light beams and the formation of speckle patterns when coherent light is scattered or reflected. We use existing physical models for these phenomena to mimic the behavior of Gaussian beams and the statistical properties of speckle patterns without performing a wa...

The controversial term ”nondiffracting beam” was introduced into optics by Durnin in 1987. Discussions related to that term revived interest in problems of the light diffraction and resulted in an appearance of the new research direction of the classical optics dealing with the localized transfer of electromagnetic energy. In the paper, the physical concept of the nondiffracting propagation is ...

Abstract A method is here proposed for predicting the field scattered by a planar junction between two penetrable lossy slabs having different features. The Geometrical Optics response is attained by extending the approach developed by Burnside and Burgener for lossless slabs. The diffraction contribution is evaluated by using a Physical Optics approximation of the equivalent surface currents d...

Invisibility and negative refraction are both applications of transformation optics where the material of a device performs a coordinate transformation for electromagnetic fields. The device creates the illusion that light propagates through empty flat space, whereas in physical space, light is bent around a hidden interior or seems to run backward in space or time. All of the previous proposal...
