This letter addresses the performance degradation of reflectarrays (RAs) in practical operation due to aperiodic arrangement and mutual coupling between units, and proposes a reflection-coefficient ...

A research team has developed a new way to measure and predict how plant leaves scatter and reflect light, revealing that ...

By combining a custom-built optical instrument with physics-based modeling and machine learning, the study shows that leaf-level optical properties ...

In a research article recently published in Space: Science & Technology, researchers from Chinese Academy of Sciences investigated the distribution of scattered waves and signal power alterations ...

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 ...

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 ...

Have you heard recommendations to use a particular termination in particular situations for good signal integrity? Have you ever wondered how to incorporate terminations in your design? While there ...

The dynamic response characteristics of high and steep slopes under the action of earthquakes and blasting was focused on, especially the frequency distribution and propagation laws, which are crucial ...
