Simultaneous observations of meteors and the equatorial electrojet at Jicamarca
… s to 3 minutes), radio wave scattering is non-specular (echoes are detected simultaneously over an $\sim$10 to 15 km altitude range centered about 97 km), and the Doppler spectra of the scattered signals contain components shifted by as much as $\sim$400 ms$\sp{{-}1}$ immediately after the …

Tensorial Impedance Surfaces for Manipulating Microwaves
… is done with reflection problems that demand non-specular reflection and polarisation conversion. A metasurface design is proposed that exhibits an effective impedance that is non-orthogonal to demonstrate that the condition is not strictly required. In the final content chapter, a method is …

A Numerical Investigation of Thermal Radiation Scattering From Configured and Random Surfaces
… geometrical correlation length and wavelength. Specular scattering diminishes with increasing surface heights, and the scattered energy in the specular scattering direction competes with other non-specular scattered energy when the incidence is oblique. A continuous reflection distribution is …

Semiclassical studies of decoherence produced by scattering
… impact implies the possibility of different non-specular outgoing beams thanks to the constructive interference of the emitted waves from each surface atom. Moreover, we still observe diffraction peaks when scattering off a lattice at finite temperature, although the peaks are here diminished …

A Study of Quantum Interference and Entanglement with Negative Optics
… in managing wave radiation. Constructive non‐specular wave scattering permits the scattering angle (β) to be other than twice that of incidence (α). This result in gross violations of the law of reflection, and significant fraction of the α, β phase space becomes accessible. A wide range …
