... The SHG enhancement is attributed to the combined effects of the spatial localization of the fundamental field in the MC spacer and the fulfillment of the phase-matching conditions. ... AlGaAs,14 AlAs/AlGaAs,15 and ZnS/SrF2 (Ref. 16) layers, or alternating layers of porous silicon (PS) with different porosities.17,18 Several approaches are used for the calculation of SHG enhancement at the PBG edges of photonic crystals. ... For SHG enhancement at the PBG edge phase matching is even more important. ...
Laboratory of Rare Earth Intermetallics . Chair of General Physics and Magneto-Ordered Matter . ... The primary research work is related to the study of magnetic phase transitions in rare earth (RE/R) intermetallic compounds with transition elements of the iron group, i.e. R-3d intermetallics. ... These works stimulated studies of different aspects of a magnetic instability of the itinerant-electron subsystem in RMn 2 , RCo 2 , and RCo 3 compounds in many research institutions and universities. ...
