Resonance and double negative behavior in metamaterials
… intervals imply the existence of propagating Bloch waves inside sub-wavelength structures. The branches of the dispersion relation associated with Bloch modes are shown to be explicitly determined by the Dirichlet spectrum of the high dielectric phase and the generalized electrostatic spectra …

Dynamical models for novel diffraction techniques in SEM
… in the column approximation. I use the two beam Bloch waves approach for electron channelling contrast imaging (ECCI) of threading dislocations (TDs) normal to the surface in wurtzite group-III nitride materials. I also introduce and use the notion of ECC-strain to study crystal features and to …

Electronic States near Surfaces - a) Analysis of calculation methods using semi-infinite boundary conditions; b) Sensitive detection using laser photoelectron spectroscopy
… functions are composed of linear combinations of Bloch waves of the converged self-consistent periodic lattice. In the vacuum region, the wave functions are composed of functions which decay or propagate into the vacuum. In the interface region, the wavefunctions are composed of extensions of the …
