Filip DominecContact: filip.dominec (a) gmail.comRelated websites: my projects on Github | Wikipedia user page | LinkedIn Academic: Google Scholar | ResearchGate | ORCID | Researcher ID Ultrashort CV: I graduated in laser technology and electrical engineering from FNSPE CTU in Prague and wrote my PhD thesis on terahertz metamaterials. Currently I work in the MOVPE laboratory, attempting to model electrical and optical behaviour of fast transistors and scintillators. In my spare time, among other, I like to repair old instruments and promote DIY scientific projects. |
Research
  |
Simulations of electromagnetic waves with python-meep FDTD computations can be fun! Hands-on tutorial on wave scattering, diffraction, surface plasmons, metamaterial behaviour etc. |
  |
Lorentz-Drude models of material permittivity Permittivity models of gold, silicon, silica, sapphire etc., ready to be supplied to python-meep to get quantitatively accurate results from the simulations. |
  |
Testing the FDM algorithm on experimental data Filter-diagonalisation method (FDM) can sometimes be superior to Fourier transform for spectral analysis, though it is far less used. I compare these methods on terahertz spectra of water vapor, showing the accuracy of FDM. Source codes included. |
Projects
  |
USB spectrometer Using a linear CCD from a scanner, a diffractive element (such as a CD), ATMega8 microcontroller and some basic optics, one can easily build a handheld USB spectrometer with ca. 5 nm spectral resolution |
  |
Casting an optical table of concrete A rigid platform for mechanical mounting of sensitive optical experiments can be made in every workshop with the procedure described. A Michelson interferometer is demonstrated that detects movement in order of several atomic distances. |
  |
FiDoStepper A surprisingly simple board that can drive three (unipolar/bipolar) stepper motors simultaneously. Microstepping, tool PWM control and communication over USB are implemented in ATMega8 firmware. Circuit schematics and firmware supplied. |
  |
FiDoCNC - a circuit board manufacturing robot A three-axis robot that engraves all connections, drills holes and finally cuts out whole board greatly speeds-up the workflow of electronics development. |
  |
Accurate sieving of microparticles A novel approach to sieving of sub-millimetre particles is presented that selects a very narrow fraction of sizes and shapes, using intense sound vibration. |
Software
  |
Printable A4 monthly calendar generator based on Reportlab, saves a printable A4 table with days as rows and hours as columns. Whole years 2015-2025 available as 12-page PDF files. |
  |
Optical granulometry of microparticles A script that processes a microscopic photograph into a statistics of particle sizes and ellipticity |
  |
How to make a DEB package with diacritics and spaces in filenames The Debian/Ubuntu installer can not handle "unsafe" file names, but it allows to run post-installation scripts to change the names as needed. An example of packaging procedure for PPA. |
