Course Contents
Initially, introductory concepts of the Theory of Electromagnetic Fields are provided (Sources of Electromagnetic Fields, Electrostatic Fields, Dielectric Modes and Boundary Conditions, Permanent Magnetic Fields, Biot-Savart Law, Magnetic Flow Density, Gauss Law, Lorenz Power). Subsequently, electromagnetic waves in space are described (Maxwell equations, sinusoidal time variations, free space conditions and wave equation, uniform plane waves in lossless media, wave polarization). Thereafter, the students are introduced to antenna theory and the fields of radiation (potential functions, wave radiation areas, far field assumption, generic calculation methodology of radiation fields by antennas, basic key antenna features, antenna as a circuit element, antenna effective length). Examples of antennas are then studied (Hertz dipole, linear dipole antenna of arbitrary length, dipole λ/2, small circular loop antenna). Finally, the fundamental elements of electromagnetic wave propagation are examined (frequency bands & services/applications, wave classification, Friis’ equation and Free Space Loss, reflection & transmission, plane-earth model).
Papers, lectures, case-studies, examples and web pages with valuable information are uploaded at the course web page (Evdoxos).
