Abstract: A new class of fundamental devices and methods for their manufacture and use. The bulk magnetic field replicators of the present invention require no precision machining or alignment to accurately reproduce magnetic fields of any complexity, nor extreme positional stability to maintain superconductivity. Such bulk devices may be formed of either low or high critical temperature superconductive materials, but are particularly adapted to formation from high critical temperature materials.

Abstract: A method and apparatus are provided for dynamically routing a plurality of simultaneous point-to-point communications through an array of repeating transceivers. Each repeating transceiver may simultaneously act as each of a transmitter of origin for one communication, a final receiver for a second communication, and a repeater for a plurality of other communications. When acting as a repeater, each transceiver applies programmed delays to information before re-transmitting, and these delays are programmed so as to route a communication through the array of transceivers along a designed path along which multiple re-transmissions from local repeating transceivers are received, aligned in time for constructive reinforcement, and retransmitted after dynamically programmable time delays.
