“…However, radio devices are normally fixed in case of M2M wireless communications, and changes in synthesis of multiple polarization vectors arriving at a device are definitive. By the way, there are many studies on reflection and transmission of electromagnetic waves [3][4][5][6] depending on the surface conditions of a scatterer waves are incident on, waves produced by reflection can be regular reflection waves that follow Snell's law known in optics, or irregular reflection waves that do not adhere to Snell's law. Interestingly, one regular reflection wave is always produced irrespective of the scatterer' surface shape and roughness, and its intensity surpass that of simultaneously produced irregular reflection waves.…”

A new radio system that deterministically uses reflection waves is proposed. This system transfers data on the rotating polarization wave (RPW), which rotates the polarization at enough lower frequency than that of propagation to digitally control it. The receiver discriminating a deterministic reflection wave of the RPW by selecting the polarization that the transmitter uses achieves good nonline-of-sight communication quality.

“…The approach taken by Canning (), as reformulated by Besieris (), is now generalized to the case when both media are lossy, a situation that occurs in layered complex materials. Each temporally dispersive material is assumed to be homogeneous, isotropic, and locally linear, as described by the frequency domain constitutive (material) relations

“…In a recent paper, Besieris () showed that the criticism raised by Canning () with regard to the different approaches to the solution of this problem (see chapter IX of ; Stratton, ; chapter 5 of ; Balanis, ; and the paper by Roy, ) was unnecessary as both were indeed correct in describing the reflection and transmission coefficients when one medium was lossless and the other lossy. A similar comparison has been given by Frezza and Tedeschi () from the viewpoint of electromagnetic power transmission.…”

Generalized Fresnel reflection and transmission coefficients are derived for both time‐harmonic TE(s)‐ and TM(p)‐polarized plane wave fields incident upon a planar interface separating two attenuative linear media, each described by a frequency‐dependent complex‐valued dielectric permittivity εjfalse(ωfalse)=εj′false(ωfalse)+iεj′′false(ωfalse), magnetic permeability μjfalse(ωfalse)=μj′false(ωfalse)+iμj′′false(ωfalse), and electric conductivity σjfalse(ωfalse)=σj′false(ωfalse)+iσj′′false(ωfalse),1emj=1,2 while maintaining the real‐valued form of Snell's law. The resultant effects of material loss on both the reflected and transmitted fields are presented, including the condition for the appearance of a polarizing angle.

“…We note here that the conventional Fresnel coefficients are derived for lossless medium and do not hold for lossy materials. Here we use the corrected equations derived for lossy media [36]. FWHM increases from 122nm to 164nm over a propagation distance of 200nm, but remains smaller than 127nm within the penetration depth.…”

Heat-assisted magnetic recording (HAMR) is a future roadmap technology to overcome the superparamagnetic limit in high density magnetic recording. Existing HAMR schemes depend on a simultaneous magnetic stimulation and light-induced local heating of the information carrier. To achieve high-density recorded data, near-field plasmonic transducers have been proposed as light concentrators. Here we suggest and investigate in detail an alternative approach exploiting a far-field focusing device that can focus light into sub-50nm hot-spots in the magnetic recording layer using a laser source operating at 473nm. It is based on a recently introduced super-oscillatory flat lens improved with the use of solid immersion, giving an effective numerical aperture as high as 4.17. The proposed solution is robust and easy to integrate with the magnetic recording head thus offering a competitive advantage over plasmonic technology. Sci. Instrum. 71(8), 3111-3117 (2000). 5. X.
