A novel differentiable approach optimizes geometric waveguide coatings, achieving substantial gains in light efficiency and uniformity for optical AR displays.

ABSTRACT: Seismic amplitude anomalies are widely used as direct hydrocarbon indicators (DHIs) to infer fluid contacts where well control is sparse, yet seismic tuning can bias amplitude-derived fluid ...

Abstract: Accurate characterization of the reflection coefficient of reconfigurable intelligent surface (RIS) is crucial for the design and optimization of RIS-assisted communication systems.

This paper presents a reflectarray antenna with an innovative dielectric mirror in the form of a discretized concave reflector. The mirror, manufactured via 3D printing, combines dielectric and air ...

High-frequency signals, like those used in 5G communications, are reflected by impedance discontinuities. Their shorter wavelengths can change their impedance. When a signal arrives at an impedance ...

Voltage Standing Wave Ratio (VSWR) is a fundamental parameter that measures the efficiency of radio frequency (RF) power transmission from a source through a transmission line to a load. A simple way ...

Abstract: Microwave energy has been extensively studied and used in various medical applications. Some of them involves the use of generator to generate, transmit, and emit the energy into human body ...

ABSTRACT: Determining the optical properties of media remains an important part of scientific research. Knowledge of these optical properties, particularly absorption and diffusion coefficients, has ...

The submergence depth directly affects the safety of semi-submersible marine structures due to that the submergence depth significantly impacts on the hydrodynamic characteristics and wave loads of ...
