The physics of WPT and wireless communication are related, but WPT is distinct from wireless transmission for transferring information (such as radio and mobile phones etc.), where the percentage of the power that is received is only important if it becomes too low to successfully recover the signal. With WPT, the efficiency is a more critical parameter and this creates important differences in these technologies. This paper presents the wireless power transmission (WPT), from past work to most recent accomplishments including recent developments, potential approaches and factors responsible for designing most critical rectifying diodes operating at terahertz/petahertz frequencies.

In the present paper, Nb/Nb2O5/Ta2O5/Nb, MIIM structure has been evaluated using WKB and TMM models for estimating the transport probability and current density. The total insulator thickness has been varied from 6–10 nm to evaluate the diode like behavior. Also, a review of different modeling methods used for determining the transport probability has been presented. The TMM model has been observed to result more realistic I–V characteristics, moreover the accurate modeling of MIM diodes requires an alternative model like Non-equilibrium green’s function (NEGF) approximations as it can be correlated with Metal-Insulator-Semiconductor (MIS) structure in nanoscale FET devices.
