Research interests
My scientific interests mainly cover electromagnetics and small antenna theory. These two areas are mutually interconnected and nowadays often accompanied by utilization and further advancement of numerous computational methods and techniques. The original motivation of my work can be summarized to a relatively simple question: “What antenna is the best one for a given application?” To address this question completely, the complete understanding of physical phenomena underlying the radiation mechanism is needed.
The theoretical findings as well as practical implementations can be used not only in small antenna design, but also in emerging technologies like nano and optical antennas, reflect arrays or superbackscaterring arrays. Selected topics actually solved within our group are listed below:

Shape synthesis
An everlasting dreaming of shape synthesis will hardly come completely true. The main difficulty is combinatorial nature of an associated optimization problem which impose NP hardness. On the other hand, there is strong evidence that a skilled and experienced designer can go pretty close... How close can we go with clever, albeit bruteforce techniques? Can we go closer? Is it possible to improve the performance with knowledge of the first differences or utilization of machine learning?

Slowed down by a factor of 10. A particular starting position determined by Monte Carlo (for details see IEEE TAP and IEEE AWPL).
 Fundamental bounds in electromagnetism
Fundamental bounds determine the best performance of a hypothetical device. They are investigated using convex optimization and matrix operators. In antenna theory, the fundamental bounds yield optimal current densities defined in prescribed region. They can be, among others, bounds on minimum antenna Q, maximum antenna gain, minimum dissipation factor, etc. Quite a few constraints can be used, e.g., constraint on selfresonance or on (only partly) controllable region. All bounds are now being transformed into their multicriteria form, i.e., Pareto fronts describing the mutual trade offs.

 (Electrically small) antennas (Source concept: modal and structural decomposition of small radiating bodies and their optimization, feeding synthesis, optimal antennas),
The Source Concept represents a promising framework providing a unified theory of the evaluation, decomposition and manipulation of electromagnetic currents in ways as yet imagined. It is a mixture of powerful techniques, both analytical and numerical, together with the idea that an electromagnetic current can be substituted into any expression relevant to small antenna design. Although the Source Concept turned out to be instructive for small antennas, it is thoroughly applicable for radiators of any electrical size and shape. The Source Concept deals with two pivotal questions:  Which geometrical shape of the radiator and which material distribution are optimal in terms of a selected tradeoff between crucial parameters?
 Where the radiator should be fed for optimal performance and how should the matching circuit be designed?

Electromagnetic theory (Stored electromagnetic energy, Q factor),
A consistent definition of stored electromagnetic energy for nonstationary fields is one of the last fundamental and still unsolved problems of classical electrodynamics. One of the key issues is the potentially infinite total energy within a timeharmonic steady state. The definition of the stored energy is encumbered with an illdefined separation of the total energy into radiated energy and stored energy, where it is assumed that the bearer of the infinity is the radiation. The main concern lies in the investigation of the radiation mechanism and subtraction of the energy associated with radiation.
Figure: Classification of techniques to determine stored energy we published in 10.1109/ACCESS.2018.2807922. 
Characteristic modes theory,The theory of characteristic modes became very popular in recent years as it constitutes a general approach to study arbitrarily shaped antennas and scatterers without prior knowledge of the feeding. In its original form, the characteristic decomposition assumes perfectly electric conducting bodies in vacuum. An investigated radiator is then transformed into the impedance operator represented by a matrix of finite extend. Generalized eigenvalue problem is then established based on the real and the imaginary part of the impedance operator. Resulting basis of characteristic currents has very special properties that will be recalled during the lecture. Since no feeding in considered, all attention is focused only on the geometry and its effects on radiation properties. In order to feed the selected set of modes, the position, amplitude and phase of the feeding need to be determined ex post.Figure: One of the first five characteristic modes (randomly selected) of randomly generated polygon (updated daily, powered by AToM :) ).

MATLAB (mainly development of the AToM package)
The last five years have allowed the capabilities of the Source Concept to be recognized and software tools associated with its implementation have begun to appear. To support this common effort and to accelerate the development of the inhouse tool TCMapp, a new project, founded by the Technology Agency of the Czech Republic, started in July 2014. An important part of the project is called the Antenna Toolbox for Matlab (AToM). The AToM package aggregates all present scientific knowhow of the Source Concept and it will remain in the ownership of Czech Technical University and Brno university of technology. The AToM is written entirely in Matlab, so the user will enjoy its semiopen architecture and friendly operation through GUI or direct access to low level functions. Main simulation core is based on Method of moments, both for 3D wire and planar structures. Together with modal decomposition (Characteristic modes), the source concept, feeding synthesis and powerful optimization (FOPS optimizer), it will present unique tool for syntesis of antennas.
 Singlecriteria and multicriteria (heuristic) optimization,
Many ingenious techniques have recently been adopted to approach the antenna synthesis as closely as possible. Single and multiobjective optimization algorithms have proved themselves to be essential tools, in particular the convex optimization and heuristic optimization techniques which can be advantageously combined with the physical machinery introduced above.

Once discovered, the fractal geometry have been immediately recognized as a fascinating branch of mathematics with many potential applications across the engineering science. This is the case of electromagnetic field theory as well. For instance, the fractal shapes are promising candidates for electrically small antennas. However, many issues needs to be solved and deeper theoretical understanding must be achieved together with discovery of new (ideally) lossless materials.
