Paper Abstract

Convectional laser-wave-communication-systems canalize only the linear momentum in time (or mutually in space) domain, therefore neglecting all the non-linear signal power related to the angular momentum and losing the related information, whilst in time-space-domain the power-information is carried by the spin-angular-momentum (SAM) the orbital-angular-momentum (OAM) and the linear-momentum (LM) related to the signals. This paper concerns with an innovative technique which uses the non-linear-power of the beam-waves-modes to canalize/extract simultaneous independent signals, in Coulomb gauge conditions and paraxial accuracy, to enable information space-time-domain-canalization with extremely large bandwidth regardless of the given frequency carrier. The paper illustrates verification tests results developed using an EM or optical laser ground-communication-system implementing a health-care-tele-assistance and patient health-care-tele-examination in data, audio and video star-link configuration using any UHF/VHF-frequency-carrier.
