Propagation of Radio \vavj’s over a Stratified Ground*
The propagation of vertically polarized radio waves over a horizontally stratified medium is investigated. A general expression for the “wave tilt” is derived for the case of any number of layers with arbitrary properties in each layer. Numerical calculations are carried out for the special case of only two layers which show that the conductivity and dielectric cxlnstanl variations of the Ionc~...
متن کاملTemperature Effects on Anomalous Radio Duct Propagation in Korean Coastal Area
Atmospheric radio ducts can trap VHF/UHF radio waves and propagate them over long distances. 284.4625 MHz Japanese radio wave signal measurements show that the radio waves are propagated to Korea coastal regions when ground temperatures exceed 10◦C. This paper discusses the reasons for the existence of this critical temperature threshold. key words: radio duct, duct propagation, critical temper...
متن کاملParameter Based Constant Propagation
JavaScript is nowadays the lingua franca of web browsers. This programming language is not only the main tool that developers have to implement the client side of web applications, but it is also the target of frameworks such as Google Web Toolkit. Given this importance, it is fundamental that JavaScript programs can be executed efficiently. Just-in-time (JIT) compilation is one of the keys to ...
متن کاملcomparative analysis of ionospheric vtec parameter and meteorological precipitation parameter in esfahan and shiraz
reduced rainfall in many parts of the world have prompted scientists to try to manipulate, in different ways, to the nature, causing precipitation from accumulated water in the atmosphere. atmospheric ionization is a new method for producing precipitation and has attracted much attention. in this regard, in recent years, in some regions of the world, in different ways, the relation between mete...
متن کاملPerformance Evaluation of Radio Propagation Models on GSM Network in Urban Area of Lagos, Nigeria
The analysis of radio propagation in urban terrains became highly imperative owing to the fact that the environment is composed of different physical obstructions such as high-rise buildings, towers and bill boards situated on a grid-like pattern of streets. Radio propagation characteristics, to a large extent, vary from one type of environment to the other. In this paper, the suitability of th...
