GHz Range SAW Transducers Using Electron Beam Lithography
(Wydawnictwo Naukowe Uniwersytetu im. Adama Mickiewicza w Poznaniu, 1990)Nanometer electrodes of the order of 0.085 μm width have been fabricated using direct electron beam lithography, normal lift-off techniques and 0₂-plasma cleaning system. These techniques have been applied to Inter-Digital ... -
Hyperfine Interactions Versus Intrinsic Symmetries of Many-Electron Systems in Near-Surface Regions
(Wydawnictwo Naukowe Uniwersytetu im. Adama Mickiewicza w Poznaniu, 1990)The paper aims at unifying various types of hyperfme interactions from the viewpoint of Finsler geometry and supercomplex structures, reflecting the intrinsic symmetries of many-electron systems, with special reference ... -

Transition Radiation Emitted from a Surface Irregularity Shaped as Rectangular Step and Rectangular Groove
(Wydawnictwo Naukowe Uniwersytetu im. Adama Mickiewicza w Poznaniu, 1990)Transition radiation emitted when a nonrelativistic particle (β=0.2-0.5) enters a surface irregularity shaped as a rectangular step and a rectangular groove and having the dielectric constant ε=1.4-3.8 has been investigated. ... -
Transition Radiation from Rough Surfaces
(Wydawnictwo Naukowe Uniwersytetu im. Adama Mickiewicza w Poznaniu, 1990)We propose a theory of transition radiation emitted by charged particles entering a rough interface between two media. We show that the radiation process is influenced by surface inhomogeneities distributed both ... -
