ELECTRONIC COMMUNICATIONS SYSTEMS Wayne Tomasi‚ 5th edition Introduction to Electronic Communications Electricity began in 1837 when Samuel Finley Breese Morse invented the first workable telegraph. In 1894‚ Marchese Guglielmo Marconi successfully transmitted the first wireless radio signals through Earth’s atmosphere. In 1906‚ Lee DeForest invented the triode vacuum tube. Commercial radio broadcasting began in 1920 when radio station KDKA began broadcasting amplitude-modulated

Laser dentistry is a relatively new form of dental care. Laser Dentistry uses lasers to perform surgery‚ prepare cavities‚ and harden dental resins. This use of lasers has allowed dentists to perform tasks with less pain and with improved results. There are many different types of lasers used in the dentistry field. Theses lasers included the argon laser‚ the diode laser‚ the neodymium: yttrium aluminum garnet (Nd:YAG) laser‚ the holmium: yttrium aluminum garnet (Ho:YAG) laser‚ the erbium: yttrium

Abstract: In this paper‚ we present the concept of transmitting power without using wires i.e.‚ transmitting power as microwaves from one place to another is in order to reduce the transmission and distribution losses. This concept is known as Microwave Power transmission (MPT). This paper is mainly concentrated on : i) The most popular concept known as Tesla Theory‚ ii) The microwave power transmission(MPT) called Solar power satellite‚ and iii) The highly efficient fiber lasers for wireless power
