Abstract: In this article, the design and implementation of a compact and portable six-port reflectometer for measuring the reflection coefficient at 2.4 GHz is presented. The proposed design utilizes ...

Abstract: This study presents the results of using a millimeter wave reflectometer system, operating at 150 GHz, for demonstrating the basic efficacy of measuring electromagnetic scattering of metal ...

时域反射计的基本原理是利用反射波来测量电路或传输线中的阻抗变化。其核心思想是在一个传输线路（如金属电缆或光纤）中发送一个脉冲信号，当信号遇到阻抗变化时（如连接器、PCB的拐角、过孔、断点等），会发生部分反射。通过测量这些反射信号的电压 ...

A new Learning Management System (LMS) instituted by Tempo Communications provides free, on-demand courses to equip ...

Distributed Acoustic Sensor (DAS) has potential in applications such as hydroacoustic detection. In this paper, a dual-pulse heterodyne distributed acoustic sensor (DAS) system using a semiconductor ...

A Smoke Stain EEL Model 43D reflectometer was used to measure the light absorption coefficient of the exposed filters to estimate the equivalent black carbon concentrations using the Virkkula et al ...

Vapor pressure deficit (kPa) was derived from AT and RH following Ward and Trimble (2003): Volumetric water content (VWC; %) and soil temperature (ST; °C) were measured at 10 cm depth on six randomly ...
