On the project

The project deals with the synthesis and description of analogue circuits – phantoms, that emulate and capture in time the electrical properties of systems/tissues being analyzes mainly using the impedance spectroscopy technique. The definition of these phantoms is based on using the fractional calculus, whereas for their realization mainly the passive fractional-order elements (or constant phase elements) and their suitable combination and transformation, which represents an area not sufficiently investigated so far. The importance of such phantoms for the future research is the possibility of explicit comparison and suitability of measurement techniques used for material characterization. Within the project, the experience of the project team in the area of analog circuit design are used, whereas the project outputs are mainly the original circuit solutions whose behavior is verified both by simulations and experimental measurements. The reached outputs are published in distinguished journal with the scope in area of this research project.

Description in Czech
Projekt se věnuje problematice syntézy a popisu analogových obvodů – fantomů, kterými jsou emulovány a v čase uchovány elektrické vlastnosti systémů/vzorků analyzovaných především metodou impedanční spektroskopie. Popis těchto fantomů je založen na využití fraktálního počtu, kdy při jejich fyzické realizaci jsou využívány zejména pasivní prvky fraktálního řádu (prvky s tzv. konstantní fází) a jejich vhodné transformace a kombinace, což je oblast, která dosud nebyla dostatečně prozkoumána. Význam takových fantomů pro budoucí výzkum spočívá v možnosti explicitně porovnat vhodnost vlastních měřicích technik využívaných pro charakterizaci materiálů. V rámci řešení projektu jsou využity zkušenosti řešitelského kolektivu v oblasti návrhu analogových obvodů, kdy výstupem projektu je především popis původních řešení obvodových struktur, jejichž chování je ověřováno jak počítačovými simulacemi, tak i experimentálními měřeními. Takto získané výstupy jsou publikovány v renomovaných časopisech, které se věnují dané výzkumné oblasti.
