Inverse Design of Mirror‐Symmetric Disordered Systems for Broadband Perfect Transmission
Laser &Photonics Reviews, EarlyView.This work introduces an inverse design approach to achieve broadband perfect wave transmission in mirror‐symmetric disordered media. Leveraging symmetry simplifies optimization and enables control of multiple reflectionless states. Experiments in microwave waveguides confirm the design of exceptional points, bandpass filters, and broadband quasi ...

Information preserved guided scan pixel difference coding for medical images
, 1995 This paper analyzes the information content of medical images, with 3-D MRI images as an example, in terms of information entropy. The results of the analysis justify the use of Pixel Difference Coding for preserving all information contained in the ...

Frozen Differential Scattering in Reconfigurable Complex Media
Laser &Photonics Reviews, EarlyView.A localized perturbation universally results in a rank‐one update of the scattering matrix of any complex medium. The resulting differential output wavefront is “frozen”: its spatial pattern is fixed (agnostic to the input wavefront). Experiments with a programmable‐metasurface‐parametrized wireless link validate frozen differential scattering and ...

Lossy compression of discrete sources via Viterbi algorithm
, 2010 We present a new lossy compressor for discrete-valued sources. For coding a sequence $x^n$, the encoder starts by assigning a certain cost to each possible reconstruction sequence.

Dipole‐Quadrupole Model and Multipole Analysis of Resonant Membrane Metasurfaces
Laser &Photonics Reviews, EarlyView.Membrane metasurfaces, arrays of holes in a dielectric membrane, are appealing because they require no substrate and allow access to resonant near‐fields. However, developing a comprehensive theoretical description for them remains challenging. We introduce a semi‐analytical dipole‐quadrupole approach to analyze their resonant spectra at arbitrary ...
