In this paper, two type of binary 2D subwavelength (wavelength was λ= 10 mm) focus diffractive photonic crystal lens and calculated the diffraction of plane TE-wave by use FDTD-method.Abstract:
We designed novel two type of binary 2D subwavelength (wavelength was λ= 10 mm) focus diffractive photonic crystal lens and calculated the diffraction of plane TE-wave by use FDTD-method (our program in C++). It has been shown that diffractive photonic crystal lens designs have not an unique solution. It has been also shown the diffractive lens with equal holes in Fresnel zones has better focusing characteristics. Lens diameter was 5 times more than her width and full width half maximum diameter of focal spot was 0.48λ.read more

TL;DR: A dielectric cuboid is utilized to generate an optical gradient force exerted on the nanoparticles for particle’s hovering and trapping and it is shown that the permittivity contrast between the particle and the nanohole leads to the deep subwavelength light confinement and enhancement at the opening of the Nanohole.

Numerical solution of initial boundary value problems involving maxwell's equations in isotropic media
Abstract: Maxwell's equations are replaced by a set of finite difference equations. It is shown that if one chooses the field points appropriately, the set of finite difference equations is applicable for a boundary condition involving perfectly conducting surfaces. An example is given of the scattering of an electromagnetic pulse by a perfectly conducting cylinder.
