In this paper the Higgs mechanism is simply explained by a modification of the Kronig-Penney-Model well known in solid state physics. By this model an inverse (harmonic) oscillator is derived which can give a hint to Higgs Mechanism, eventually the H

In this paper, a very simple novel model is presented concerning the unified field theory (“theory of everything”). In the scope of this novel theory, it is assumed that matter, space and time are quantized. It is assumed that the space is subdiv

Polymethylmethacrylate (PMMA) substrate was covered with liquid 1,2,3,5-tetrafluorobenzene by spin coating. Then the sample was irradiated by a KrF-excimer laser ( λ = 248 nm). Thus, fluorine is released from the fluorine-containing precursor diffus

PMMA (Polymethylmethacrylate) substrate was covered with 1,2,3,5-tetrafluorobenzene by spin-coating. Then the sample was irradiated by a KrF-excimer laser ( λ = 248 nm). After drying out the polymeric substrate, the sample surface was investigated b

In this paper first experimental results are presented on the fabrication of integrated-optical microstructures by femtosecond-laser irradiation at the surface or in the volume of a polymeric substrate. Thereby the refractive index or the optical abs

An integrated-optical strip-waveguide is directly written into the surface of a planar polymer substrate by an excimer laser beam. The mode field distribution, the surface refractive index and the refractive index depth profile of the waveguide have

Surface relief gratings are written into the surface of a planar PMMA substrate by the UV-excimer laser based phase mask method. The surface relief grating topography (grating amplitude and grating constant) is investigated in dependence on the laser
