INTEGRATED Engineering Software, a developer of hybrid simulation tools for electromagnetic design analysis, announced that its latest version of SINGULA now handles highly lossy materials.

Lossy materials exposed to electromagnetic waves generate heat. SINGULA affectively simulates applications such as this by accurately calculating the power loss in the lossy materials. The loss calculations can then be used by the company's thermal analysis software to calculate the thermal distribution. An example of this would be an antenna radiating in the presence of highly lossy materials like biological matter (like an antenna in a cellphone).

The Integral Equation method, used in SINGULA, can be an effective method for dealing with electrically large problems. Numerical results have shown that SINGULA can deal with electrically large problems with high lossy materials by making use of the Fast Fourier Transform (FFT) method.

The generalized hybrid method that combines Method of Moments (MoM) with Physical Optics, and the FFT method are also available for handling electrically large problems. INTEGRATED software allows estimating the radar cross section of arbitrarily shaped conducting bodies coated by electrically lossy materials.

For midsized problems, SINGULA uses an advanced direct solver where the matrix will fit on a hard disk but not in RAM. This advanced direct solver is based on an outer-core technique using OpenMP and a block matrix technique.

INTEGRATED’s simulation tools were developed specifically for engineers and scientists who design radio frequency, high frequency and microwave devices and components.
