Near Field Analysis
SINGULA accurately calculates near fields of antennas and of any other electromagnetic devices. There is no restriction on the distance from the antenna at which the near field analysis can be performed. The near field quantities are displayed as graphs, arrow plots or contour plots, based on the designer’s preferences. Induced electric and magnetic currents on the material interfaces can be calculated, as well as Poynting vector distribution on an arbitrary surface.
Some examples: Bird cage coils for MRI applications and RF identification devices. Simulations can include lumped R, L, C elements in SINGULA.
