Syllabus

The course presents the laws of Electromagnetism with the assumptions introduced by Modern Physics, clearly, briefly and precisely. It also contains methods and techniques for the determination of important physical quantities referring to the electrostatic field, the induction phenomena, the electromagnetic wave oscillations and the wave and particle properties of e-m waves (reflection, refraction, polarization, interference, diffraction, photoelectric effect) and to the electric conductivity of semiconductors.
