Professor Tobon’s research involves using continuum level modeling and simulation to characterize complex electromagnetic systems and phenomena (Maxwell’s equations). He focuses on reducing the computational complexity of FETD methods to characterize electrically resolved structures on large-scale systems, with explicit and implicit temporal integration, based on computational domain decomposition. The applications span from 3D microelectronics, from nanometers to millimeters, design of wide band antennas interacting with large electrically active structures, and dispersive media detection (e.g. anti-personal land mines, improvised explosive devises). Other research interests involve the use of orthogonal functions to perform signal analysis for classification problems. Among these, we are currently studying sound as a means to diagnose health in ecosystems.
