Abstract
Systems are configured to detect advanced fields, and are therefore able to provide instantaneous communications, radar detection, and remote telemetry. Receiving stations in communications systems and some telemetry systems communicate by modulating a variable termination resistor across the receiver's input terminals. Radar systems and some telemetry systems are sensitive to differential absorption at the targets.
Claims10
A communications system comprising a transmitting station and a receiving station separated by a distance that results in a particular time-of-flight interval, wherein:
- A(1) the transmitting station comprises,
- a transmitting-station antenna subsystem,
- a transmitting section, and
- a receiving section;
- A(2) the transmitting section comprises,
- a transmitting-station transmitter, and
- a first transmitting-station feedline coupled to the transmitter at one end and to the transmitting-station antenna subsystem at the other end;
- A(3) the receiving section comprises,
- a transmitting-station receiver, and
- a second transmitting-station feedline coupled to the transmitting-station antenna subsystem at one end and to the transmitting-station receiver at the other end;
- A(4) the receiving station comprises,
- a receiving-station antenna subsystem,
- a receiving-station feedline,
- a receiving-station receiver having input terminals,
- a variable terminating resistor across the receiving-station receiver's input terminals, and
- a mechanism for modulating the resistance of the terminating resistor with signal information to be communicated to the transmitting station;
- B(1) electrical signals generated by the transmitting-station transmitter are communicated along the first transmitting-station feedline to the transmitting-station antenna subsystem, which provides retarded radiation directed toward the receiving station;
- B(2) the retarded radiation directed toward the receiving station impinges on the receiving-station antenna subsystem and electrical signals are communicated on the receiving-station feedline to the receiving-station receiver;
- B(3) the modulation of the load resister generates advanced and retarded signals in the receiving-station feedline, which are communicated to the receiving-station antenna subsystem, resulting in (a) a retarded wave propagating outward from the receiving station, and
- (b) a time-reversed advanced wave from infinity converging on the receiving station at the same time that the retarded wave diverges from the receiving station;
- B(4) the advanced radiation converging on the receiving station reaches the transmitting station earlier than it reaches the receiving station by the particular time-of-flight interval;
- and
- B(5) the advanced radiation received by the transmitting-station antenna subsystem is communicated along the second transmitting-station feedline to the transmitting-station receiver.
A transmitting station for use in a communications system where the transmitting station sends retarded electromagnetic waves to a receiving station, and receives advanced and retarded electromagnetic waves from the receiving station in response to the set retarded electromagnetic waves, the transmitting station comprising:
- a transmitting-station antenna subsystem;
- a transmitting section comprising,
- a transmitting-station transmitter, and
- a first transmitting-station feedline coupled to the transmitting-station transmitter at one end and to the transmitting-station antenna subsystem at the other end;
- and
- a receiving section comprising,
- a transmitting-station receiver, and
- a second transmitting-station feedline coupled to the transmitting-station antenna subsystem at one end and to the transmitting-station receiver at the other end;
- wherein (a) electrical signals generated by the transmitting-station transmitter are communicated along the first transmitting-station feedline to the transmitting-station antenna subsystem, which provides retarded electromagnetic waves directed toward the receiving station, and (b) electrical signals generated by the advanced electromagnetic waves from the receiving station are communicated along the second transmitting-station feedline to the transmitting-station receiver (c) the signals resulting from the received electromagnetic advanced waves arrive at the same time as the signals from the transmitting-station transmitter are generated.
A receiving station for use in a communications system where a receiving station receives retarded electromagnetic waves from the transmitting receiving station, and sends advanced and retarded waves to the transmitting station, the receiving station comprising:
- a receiving-station antenna subsystem;
- a receiving-station receiver having input terminals,
- a variable terminating resistor across the receiving-station receiver's input terminals;
- a receiving-station feedline coupled to the receiving-station antenna subsystem and the receiving-station receiver;
- and
- a mechanism for modulating the resistance of the terminating resistor with signal information to be communicated to the transmitting station;
- the modulation of the resistance of the terminating resistor generates signals in the receiving-station feedline, which are communicated to the receiving-station antenna subsystem, resulting in
- (a) a retarded wave propagating outward from the receiving station, and
- (b) an advanced wave propagating inward from infinity to the receiving station,
- wherein the retarded and advanced waves are time-reversed versions of each other so that the advanced wave converges on the receiving station at the same time that the retarded wave diverges from the receiving station.
