Research groups

Antennas

We are focused on theory and design of antennas, sensors and electromagnetic compatibility issues. Our work is supported by sophisticated software design tools CST Studio, FEKO, IE3D and Microwave Office. We also develop our own numerical codes in MATLAB. Our department is equipped with workroom and anechoic chambre, where the antennas can be precisely measured. 

Computational Electromagnetics (CEM)

The group of Computational Electromagnetics is mostly active in the area of the electromagnetic field theory. Members of the group participate in courses on electromagnetic field theory and Matlab programming. Currently, we are interested in analytical works concerning electromagnetic energy, matrix description of field quantities, topological optimization, problems of structural synthesis and in implementations of various numerical schemes for electromagnetic field modelling. The leading objective of the group is a development of a scheme for automated design of generic radiators and reflective surfaces.

EM Field in Medicine and Industry

Our research interests are studies of EM field interactions with a matter, especially with biological systems. Studying these interactions we are trying to identify biological effects of EM field (above all those positive, which is possible to use in medicine for development of new treatment methods). EM field with matter interaction studies can be used for environmental technologies in industry. 

Microwave circuits, systems and measurement

Our research group works in the field of RF and microwave techniques in all its forms and in the frequency band from “nearly DC” up to tens of GHz. We design and create individual circuits, progressive complex communication, detection or measurement systems, in addition to developing new measurement methods. We work with top CAD design tools including circuit and system simulators featuring Microwave Office (AWR) and ADS (Keysight Technologies), as well as 3D electromagnetic field simulators such as Microwave Studio (CST) and HFSS (Ansoft), not to mention high-tech measurement instruments covering frequency bands up to 110 GHz. 
Our latest projects focus on researching the measurement of extreme impedances in microwave frequencies (in a project financed by the EU), the development of radar sensors operating at 16 GHz and 35 GHz frequency bands (for the Ministry of Defense of the Czech Republic), the development of microwave sensors to measure small distances precisely (TAČR), and the development of methods for the measurement of EMC filters in the GHz frequency band (for the National Security Authority of the Czech Republic). We promote the development of microwave techniques, cooperate with both large and small research teams and firms on a range of projects of varying size.

Radiowave Propagation

Researching propagation channels in a variety of environments focusing on both atmospheric and local environment effects. Developing propagation models for the planning of advanced wireless systems. Propagation channel characterization for UAV, satellite and terrestrial applications amongst others. 

Wireless and Fiber Optics

The optical research team engages in fiber optics, optical sensing, fiber lasers, optical beam outdoor and indoor propagation with respect to atmospheric influence on free-space optic (FSO) links and last but not least in visible light communication (VLC). Currently our scientific effort is focused on fundamental research as well as on cooperation with industry in the field of applied research.
