Electromagnetic field and Electromagnetic waves * * Lecturer： Email： Class hours： Introduction 1.what this course is about and the main content 2.the development of EM theory EM technology 3.the practical works and applications of EM 4.Assessment methods and module aims A branch of physic， focus mainly on： macroscopical field theory microscopic quantum electrodynamics main research field of EM theoretical basis of radio-technology， focus mainly on: research of three important application problems 1.what this course is about and the main content ★Three important application problems: ☆ EM field（or EM wave）, a form of energy，is the most important energy in the world. This field of research involves generating, storage, transforming, transmissing and comprehensive utilization of EM energy ☆ EM wave, the carrier of information transmission, is becoming the main method to transmitreceive information for the human society. This main research field is focusing on generating, capturing, exchanging, transmissing, storing, reconstructing and comprehensive utilizing information. ☆ EM wave, an important method of detecting the unknown worlds, focuses mainly on interreactions between the research target and EM wave, capturing and reconstructing target characteristics, detecting new techniques. the main content of the module: 1). Vector and vector operation. (mathematical foundation) 2). Electrostatic field. (electrostatic charge, constant current) Coulombs Law, 3).magnetic field of constant current. (constant current) oersteds Law, 4). Time-Harmonic EM Field and EM wave. (time-varying) Faradays Law, interaction of time-varying E M, Maxwells equations 5). Transmission line. coaxial-line ( oscilloscope ) 6).Waveguide. rectangular waveguide 7). Radiation and reception of EM wave antenna Teaching materials: 1.杨如贵(译著)，Robert R.G.
