| ABSTRACT:
The present invention provides passive networks which act as the
host to nonlinear and parametric interactions, with energy inputs to said
networks being caused to "bleed off" auxiliary, and time-delayed conditioning
flows resulting in phase modulations to the main input and which achieve,
e.g., RF phase conjugation with cancellation of the noise modulation after
two-way passage of beams between transmitter and receiver and when used
in duplex arrangements. Also, passive networks for noise reduction in communications
transmission due to conditioning of electromagnetic fields in higher order
group symmetry form. Because atransmitted wave from a network of the present
invention is in higher-order group symmetry form, and fields of such higher-order
symmetry have a low probability of occurrence naturally, then environmental
noise, which is of lower group symmetry form (usually, U(1) symmetry) and
has a high probably of natural occurrence, will be excluded from a receiver
matched to higher-order symmetry waves. Therefore in the case of communications,
less noise will be processed statistically at a receiver designed for SU(2)
or higher group symmetry operation, resulting in enhanced signal-to-noise.
Also disclosed are passive networks for power transmission resulting in
decreased loss in transmission. Higher-order group symmetry matched "receivers"
will have enhanced signal-to-noise reception over lower-order symmetry
receivers, i.e., leakage to ground will be less. |
