Abstract

An electronic device and associated methods including magnonic and electronic circuitry are disclosed. In one example, an array of magnonic elements are interconnected to form a network of spin wave paths, and an electronic pathway is connected to the network of spin wave paths to form a ring circuit.

Claims (9)

1. A magnonic active ring device, comprising:

an array of magnonic elements interconnected to form a network of spin wave paths; and

an electronic pathway, including a phase shift circuit and an attenuation circuit, wherein the electronic pathway is coupled with the network of spin wave paths to form a ring circuit.

2. The magnonic active ring device of claim 1 , further including a number of output detectors located on a side of the array of magnonic elements.

3. The magnonic active ring device of claim 1 , wherein the array of magnonic elements includes an array of magnets that are selectively polarizable.

4. The magnonic active ring device of claim 3 , further including programming circuitry to selectively polarize individual magnets in the array of magnets.

5. The magnonic active ring device of claim 4 , wherein the programming circuitry is configured to accept data in relation to a mathematical problem and to polarize corresponding magnets in the array of magnets to solve the mathematical problem.

6. The magnonic active ring device of claim 5 , further including circuitry to gradually reduce an attenuation in the attenuation circuit until a shortest resonant pathway is identified in the network of spin wave paths.

7. The magnonic active ring device of claim 6 , wherein the number of output detectors are configured to characterize the shortest resonant pathway and to relate a characterization of the shortest resonant pathway to a solution of the mathematical problem.
