The electric field at the output of an optical system is in general affected by both aberrations and diffraction. Many simulation techniques treat the two phenomena separately, using a geometrical propagator to calculate the effects of aberrations an

We study a simulation method that uses the Wigner distribution function to incorporate wave optical effects in an established framework based on geometrical optics, i.e., a ray tracing engine. We use the method to calculate point spread functions and

In this work we present results on the practical realization of optical negative-index metamaterials based on two different geometries for the visible and near infrared (NIR) domains. A detailed description of the manufacturing technology used for th

Influence of the short-range lateral disorder in the meta-atoms positioning on the effective parameters of the metamaterials is investigated theoretically using the multipole approach. Random variation of the near field quasi-static interaction betwe

Metamaterials are composites consisting of artificial meta-atoms/metamolecules with typical sizes less than the wavelength of operation. One of the key properties that makes metamaterials distinctly different form the natural media is a very strong m

Homogenization of optical metamaterials is one of the fundamental problems of electrodynamics of composite materials. Here the homogenization approach using multipole expansion is analysed and compared with the phenomenological one. Applications of t

Plasmonic nanostructures exhibit a strong field enhancement due to the excitation of localized and propagating surface plasmon polaritons. The use of these effects yields in a wide range of analytical applications. For instance, the strong electromag

We study the physics of a new type of subwavelength nanocavities. They are based on U-shaped metal-insulator-metal waveguides supporting the excitation of surface plasmon polaritons. The waveguides are simultaneously excited from both sides of the U

An alternative way to determine the dispersion relation and the effective material parameters is presented. The introduced model can be applied to treat the double wire as well as the split ring resonator geometry, while the first one is presented in
