Atomics and optics

Subject description

In the introduction, we explain the physical basis of electromagnetism and Maxwell's equations. Then we continue with the mathematical description of electrical conduction in metals and electrolytes. After that, we devote ourselves to modeling the dielectric properties of solids and liquids. In the following, we derive Poisson's equation and, as a special example, the Poisson-Boltzmann equation to describe the electric double layer that is formed when a metal surface is in contact with electrolyte solution. In the chapter on the magnetic properties of matter, we explain the main characteristics of the physical models of diamagnetism, paramagnetism and ferromagnetism. The chapter on optics begins with a mathematical description of electromagnetic waves. We also discuss total reflection and optical fibers and examples of simple devices from geometrical optics. In the part of lectures on modern physics, we first explain the basics of the theory of special relativity, then the photo effect, black body radiation and finally the origin of X-rays and their applications. In the final part devoted to the understanding of the main properties of the atoms, we describe the Bohr model of atom which is then used to explain the emission line spectra of gases.

The subject is taught in programs

Expected study results

The acquired knowledge in the fields of atomics and optics will enable the students to better understand the electrical properties of the materials which are important in electrical engineering. The students will acquire a general education in atomics and optics and also gain better understanding of theoretical and experimental methods which are used in electrical engineering.

Successful completion of the course will provide the students with:

education in fundamental atomics and optics, preparing them for a future as problem solvers in the industry,
a good basic education in atomics and optics suitable for a career in the industry from teh field of electrical enginerring.

After completion of the course the students should be able to/of:

use the basic theoretical tools of atomics and optics that are needed for the more specialised courses in electrical engineering,
application of the basic laws of atomics and optics to solve general problems in electrical engineering,
solve practical problems in engineering , which prepare the students for independent development work in the industry,
solve interdisciplinary engineering problems, requiring a knowledge and understanding of atomics and optics, as well as experience with analytical tools from the field of physics.
