This study has investigated the wettability of forewings of 15 species of cicadas, with distinctly different wetting properties related to their nanostructures. The wing surfaces exhibited hydrophilic or weak to strong hydrophobic properties with contact angles ranging from 76.8 deg. to 146.0 deg. The nanostructures (protrusions), observed using environmental scanning electron microscopy (ESEM)...

A new path loss model of interference between mobile terminals in a residential area is proposed. The model uses invertible formulas and considers the effects on path loss characteristics produced by paths having many corners or corners with various angles. Angular profile and height pattern measurements clarify three paths that are dominant in terms of their effect on the accurate modeling of ...

The paper presents the results of studies polarization backscattered optical radiation for a model sphere with wavy surface covered arbitrarily oriented ellipsoidal pores. calculations were performed by Monte Carlo method (ROKS-RG program, geometrical optics approximation). Surface roughness objects is taken into account using local geometries. It shown that structures whose pores contain vitre...
