Research

My research focuses on simulation-driven computer aided design (CAD) for RF/microwave and light-wave engineering. Current projects include development of robust, numerically-efficient, and accurate approaches, which should be also feasible and convenient for implementation by industry engineers. These projects use simulation-driven surrogate based design-optimization as the core methodology. Application includes antenna design, substrate-integrated circuit (SIC) component design, lightwave component design, i.e., the areas where fast and reliable surrogates originate from properly corrected and handled full-wave coarse-discretization simulation data. The main challenge here is developing CAD techniques that are capable to combine knowledge of the engineer and self-adjusting optimization algorithms for fast and reliable designs.
