| Popis: | Antenna technology provides the crucial interface between electronic devices and electromagnetic waves required for wireless communications. This technology has operated under largely the same general principles for over a century, resulting in stagnation of advancements in modern times and fundamentally limiting the extent to which potential applications of wireless communications may be realized. Herein we propose a novel concept for antenna operation employing the nonlinear precession dynamics of subatomic spins. An electromagnetic wave incident on a precessing spin will serve to modulate the spin frequency of precession. Antennas operating based on a detection of these spin dynamics are then able to fully characterize the incident wave while achieving substantial amplifications, higher sensitivities, and smaller form factors as compared to conventional antennas. A preliminary experimental implementation of the proposed concept establishes its feasibility and is already able to demonstrate significant amplification and size benefits.
