H-Matrix

Electric fields calculated in a populated PC system: a metallic enclosure of dimensions (20x20x10 cm) contains a Mini-ITX mainboard with attached RAM modules and a CPU/heatsink configuration. In the depicted field distribution (8GHz), a monopole antenna is used to represent the RF excitation of the CPU. At these frequencies, 100000 unknowns are required to discretize the surface current distribution. The numerical calculation could be performed in less than an hour on four cores – including the evaluation of the electric fields at more than one million observation points. (Source: TET, TUHH)
