Worst cases for an one-hop high frequency link
ionosphere radio propagation worst cases ray-tracing
2015/9/25
The characterisation of a HF channel by means of monthly electron density profiles can be complemented with a detailed study of radio propagation «worst cases» on situations with extremes co...
A priori estimates for high frequency scattering by obstacles of arbitrary shape
high frequency scattering bstacles of arbitrary shape
2010/12/27
High frequency estimates for the Dirichlet-to-Neumann and Neumann-to-Dirichlet operators are obtained for the Helmholtz equation in the exterior of bounded obstacles. These a priory estimates are use...

Strain-mediated magnetoelectric magnetostrictive/piezoelectric heterostructures high frequency effects
2010/11/19
Magnetoelectric coupling terms are derived in piezoelectric/magnetostrictive (multiferroic) thin film heterostructures using Landau-Ginzburg free energy expansions in terms of strain and by con-sideri...
Influence of high frequency and moderate energy pulses on DLC deposition onto metallic substrates by magnetron sputtering technique
diamond-like carbon corrosion implantation surface characterization
