This paper concerns propagation of transient electromagnetic waves in laterally discontinuous dispersive media. The approach, used here, employs a component decomposition of all fields. Specifically, the propagation operator that maps a transverse field on one plane to another plane is specified. Expansion of this mapping near the wave front determines the precursor or forerunner of the problem.

This thesis explores the possibility of using advanced device geometries and heterostructure engineering to manipulate, control, and study the electrical and optical properties of semiconductor nanowires. The first part of the thesis investigates the use of different gate-all-around architectures for creating new types of gate-controlled nanowire devices, primarily intended for fundamental studies

In recent years, contact-induced language changes have been hotly discussed (e.g. Heine 2003; Heine and Kuteva 2005), and in this paper, a similar line of argument is presented concerning the Slavic languages, and a similar developmental path is applied to minority languages. Based on analogy, future state of minority languages is predicted.
Some languages in the Indo-European family are know

Optical spectroscopy, and in particular laser spectroscopy, provides numerous possibilities for advanced diagnostics and multi-spectral imaging with real-time capability. We describe applications to the environmental and medical fields and it is noted that the basic approaches are very similar in both areas. Environmental diagnostics discussed includes satellite imagery, long-path absorption atmos

The all spectrum absorption efficiency appears in the physical bounds on antennas expressed in the polarizability dyadics. Here, it is shown that this generalized absorption efficiency is close to $1/2$ for small idealized dipole antennas and for antennas with a dominant resonance in their absorption. Also, the usefulness of this parameter is analyzed for estimation of antenna performance. The res
