We report on the experimental and numerical demonstration of immersed submicron-size hollow focused spots, generated by structuring the polarization state of an incident light beam impinging on a micro-size solid immersion lens ( μ -SIL) made of SiO

In optical systems often components of widely varying scales occur. The scale, expressed in units of wavelength, determines what kind of model is needed for the component. For objects with size of the order of the wavelength, rigorous electromagnetic

Results of ab initio calculations on the crystalfield splitting in KNiF3 are presented and discussed. It is argued that magnitude and sign of these splittings can be understood in terms of the ionic model provided that the Born repulsion terms are pr

The use of waveguide structures is examined to improve the efficiency of evanescent field coupling into zero-mode waveguides. Model calculations show that waveguide excitation using diffractive structures, increases the magnitude of the evanescent el

We present a systematic study of the effect of variation of the zinc oxide (ZnO) and copper indium gallium (di)selenide (CIGS) layer thickness on the absorption characteristics of CIGS solar cells using a simulation program based on finite element me

Polarization gratings can be realized by polarization holographic recording in photoanisotropic materials. In this paper, we study two types of polarization gratings. One is recorded with two orthogonally circularly (OC) polarized beams and the other

We present a three-dimensional model based on the finite-element method for solving the time-harmonic Maxwell equation in optics. It applies to isotropic or anisotropic dielectrics and metals and to many configurations such as an isolated scatterer i

The polarization induced by the mask is studied by using a 3D rigorous model, which solves Maxwell equations using the finite element method. The aerial image depends strongly on the change of polarization induced by the materials, thickness of the l

In many branches of optics such as optical recording and near field optics the interaction of light occurs with structures of the size of the order of the wavelength. In optical recording, metals like aluminium are encountered and when light is scatt
