Spin Hall effect of a light beam in anisotropic metamaterials

Chinese Physics B 2012年第12期21卷 236-242页

We theoretically investigate a switchable spin Hall effect of light （SHEL） in reflection for three specific dispersion relations at an air-anisotropic metamaterial interface. The displacements of horizontal and vertical polarization compo- nents vary with the incident angle at different dispersion relations. The transverse displacements can be obtained with the relevant metamaterial whose refractive index can be arbitrarily tailed. The results of the SHEL in the metamaterial provide a new way for manipulating the transverse displacements of a specific polarization component.

Influence of aircraft surface distribution on electromagnetic scattering characteristics

In this paper,two typical stealth aircraft concepts（wing fuselage blended and flyingwing） were *** three gradually changed surface distribution models with the same planform for each concept were *** on the multilevel fast multipole algorithm（MLFMA）,the vertical polarization transmitting/vertical polarization receiving（VV） and horizontal polarization transmitting/horizontal polarization receiving（HH） radar cross section（RCS） characteristics were simulated with five frequencies between 0.1 and 1.0 *** influences and mechanisms of aircraft surface distribution on electromagnetic scattering characteristics were *** results show that for the wing fuselage blended concept,the W RCS of this frequency range is higher than the HH RCS in most cases,while it is just the opposite for the flying-wing *** for the two aircraft concepts,the RCS levels of HH and W both decrease with the frequency increasing,but the HH RCS has a faster downward *** surface distribution has little influence on HH RCS *** the contrary,it has a significant impact on W RCS characteristics,and the amplitude of the VV RCS increases with the surface thickness.
