The aim of this work is to continue the analysis, started in [10], dynamics a point-mass particle $ P moving galaxy with an harmonic biaxial core, whose center sits Keplerian attractive (e.g. Black Hole). Accordingly, plane \mathbb{R}^2 divided into two complementary domains, depending on whether gravitational effects galaxy's mass distribution or Hole prevail. Thus, solutions alternate arcs hy...

This paper reports investigation of negative refraction by measurement of lateral displacement of the beam refracted at the slab made out of ‘backward-wave’ meta-material. The meta-material was based on parallel plate waveguide loaded with double ring resonators. The slab was illuminated by 8 GHz microwave beam at several different angles of incidence. The beam was generated by horn antenna and...

From the fundamental requirement of causality, we derive a rigorous criterion of negative refraction (left-handedness). This criterion imposes the lower limits on the electric and magnetic losses in the region of the negative refraction. If these losses are eliminated or significantly reduced by any means, including the compensation by active (gain) media, then the negative refraction will disa...

We show that nanosphere dispersed liquid crystal (NDLC) metamaterial can be characterized in near IR spectral region as an indefinite medium whose real parts of effective ordinary and extraordinary permittivities are opposite in signs. Based on this fact we designed an electro-optic effect: an external electric-field-driven switch between normal refraction, negative refraction, and reflection o...
