Space-time scattering network for inverse design and tomography

A method for generating a space-time scattering network (STSN), the method comprising:

• representing, by a computing unit, scattering of light through a material mathematically as a tensor field at a location;
• generating, by the computing unit, a subnet that represents the tensor field at the location;
• identifying, by the computing unit and based on a translation operator, connections between a plurality of subnets, wherein each of the subnets in the plurality of subnets represents a given tensor field at a given location;
• forming, by the computing unit, the STSN based at least in part on the identified connections between the plurality of subnets;
• and
• using, by the computing unit, the STSN to inversely design an optical component or to perform tomography.

A tangible computer-readable medium having computer-readable instructions stored thereon that, upon execution by a processor of a computing system, cause the computing system to:

• represent scattering of light through a material mathematically as a tensor field at a location;
• generate a subnet that represents the tensor field at the location;
• identify, based on a translation operator, connections between a plurality of subnets, wherein each of the subnets in the plurality of subnets represents a given tensor field at a given location;
• form a space-time scattering network (STSN) based at least in part on the identified connections between the plurality of subnets;
• and
• use the STSN to inversely design an optical component or to perform tomography.
