Methods, devices, and systems for processing information are disclosed. An example device may comprise a metastructure comprising a plurality of physical features configured to transform an analog signal according to a kernel of an integral equation. The device may comprise one or more waveguides coupled to the metastructure and configured to recursively supply a transformed analog output signal of the metastructure to an input of the metastructure to iteratively cause one or more transformed analog signals output from the metastructure to converge to an analog signal representing a solution to the integral equation.

Metastructures for solving equations with waves

The present invention is directed to the use of dielectrophoretic forces for the arbitrary manipulation of micrometer- and nanometer-sized particles and to devices capable of arbitrarily manipulating micrometer- and nanometer-sized particles by means of dielectrophoretic forces within a two- or three-dimensional region. The devices and methods of the invention are capable of arbitrarily controlling the velocities, locations, and forces applied to a particle, arbitrarily specifying a force or set of forces at a location in space, and determining friction and/or drag coefficients of a particle, and are thus well-suited for a range of applications including cell sorting, drug delivery, as a diagnostic tool for determining membrane stiffness, and in the heterogeneous integration of micro- and nano-components through directed assembly.

System and method for controlling nanoparticles using dielectrophoretic forces

Far-field sub-diffraction optical lenses 'FaSDOLs' comprise an anisotropic crystal having special dispersion characteristics such that it supports diffraction free propagation. An image with subwavelength features on the input surface is transferred through a propagation function to the output surface with effectively no, or minimal, loss in information. These special properties may be exploited in several ways, including but not limited to, magnification of an image at the input surface through the use an oblique cut at the output surface, magnification of an image at the input surface through use of a curved crystalline structure, and more generally near-field optical processing.
