Dr Alexander Goncharov
Hi, I am a PDRA with Prof. Thomas Schrefl in the area of numerical modelling of functional materials.
My current project is focused on a Time Domain Finite Element (TDFE) modelling of electric properties in electroceramics in collaboration with Prof. Derek Sinclair.
Previous projects:
EU FW6 Project MAFIN (Magnetic Films on Nanospheres) – micromagnetic simulations of magnetic recording on magnetic nanocaps.
FE micromagnetic simulations of perependicular magnetic recording in collaboration with Samsung.
Key interests:
1. Micromagnetic theory and applications to magnetic recording.
2. Low rank tensor product approximations for fast field integration.
3. Finite Element Modelling of electric properties of ceramic materials.
