SimultaneousObservation
- Very Low Frequency (VLF) spectrograms show sometimes sets of lines called MLR (Magnetospheric Line Radiation) with frequency spacing close to 50 or 60 Hz. It is very tempting to attribute these MLR to Power Line Harmonic Radiation (PLHR). PLH

Antennas
- An antenna (or aerial) is an electrical device which couples radio waves in free space to an electrical current used by a radio receiver or transmitter. In reception, the antenna intercepts some of the power of an electromagnetic in order to produce
4.2.4.5-Packet-Tracer---Connecting-a-Wired-and-Wi
- The most common wireless technologies use radio. With radio waves distances can be short, such as a few meters for television or as far as thousands or even millions of kilometers for deep-space radio communications. It encompasses various types of f
Horn_Corrugation_Design
- The corrugations present a capacitive reactance to the passing wave. When a corrugated surface is inductive, it will support surface waves. The depth of corrugations must be between λ/4 and λ/2. Less than λ/4 or greater than λ/2, it is inductive. Bet

水声通信技术综述_贾宁
- 受制于严重的衰减，电磁波在水中的传播距离非常有限，因此以声波为载 体的水声通信是在水下实现无线信息传输的主要方式。水声通信无论是在军事方面还是在民 用方面都有重要的作用，随着人类加快开发海洋的步伐，对水声通信技术的需求也变得越来 越迫切。文章对水声通信技术进行了综合介绍。首先介绍了水声通信的概念和意义，着重分 析了水声信道的特点以及水声通信面临的困难，然后对目前应用较多的几种典型水声通信技 术进行了介绍，最后对水声通信技术的发展方向进行了展望。(Due to severe attenu
