Bioinspired Tissue Transparency: Achieving Sclera‐to‐Cornea Transplantation
Advanced Science, EarlyView.A bioinspired decellularization‐compression‐locking tactic (DCLT) is developed to transform human sclerae into transparent corneal substitutes. These clear, robust, and pro‐regenerative substitutes are capable of repairing complex corneal injuries, including chemical burns, keratoconus, and penetrating wounds, demonstrating their clinical potential to ...

Determination of mean surface position and sea state from the radar return of a short-pulse satellite altimeter [PDF]
, 1972 Using the specular point theory of scatter from a very rough surface, the average backscatter cross section per unit area per radar cell width is derived for a cell located at a given height above the mean sea surface.

Super‐Robust Telecommunications Enabled by Topological Half‐Supermodes
Advanced Science, EarlyView.Through topological half‐supermode engineering, we realize a valley‐ridge gap waveguide that is directly compatible with conventional waveguides and features topological protection. This design halves the lateral size via a PEC boundary, enabling direct TE₁₀‐mode matching and robust bend‐immune transmission.

Calculation of Aircraft Target’s Single-Pulse Detection Probability
Journal of Aerospace Technology and Management, 2015 The original radar cross section data or some rough models are often used to estimate a given aircraft target detection probability. The calculation results may not be very accurate as targets are different from one another and the real radar detection ...

Effects of range bin shape and Doppler filter response in a digital SAR data processor [PDF]
In calibrating the backscatter coefficient obtained with an imaging synthetic aperture radar (SAR) system to determine absolute values of radar cross-section and reflectivity it is common practice to use a target of known radar cross-section placed ...
