Integrated Engineering Software has released the latest version of its Singula modelling software for antenna analysis, which now handles highly lossy materials.
Singula was developed specifically for engineers and scientists who design radio frequency, high frequency and microwave devices and components. Singula effectively simulates the power loss that occurs as a result of the heat generation produced when lossy materials are exposed to electromagnetic waves. The loss calculations can then be used by thermal analysis software to calculate the thermal distribution.
Singula analyses all antennas including wire, surface and dielectric. RFID devices and bird cage coils for MRI applications are also modelled using this simulation tool. Other applications for Singula are scattering calculations, microwave circuits, and shielding for electromagnetic compatibility and interference (EMC-EMI).
Singula is a generalised hybrid method that combines, in the same package, the method of moments (MOM) with physical optics, and the fast fourier transform (FFT) method to give engineers the option to choose the solver that best suits their needs. Engineers can select the MOM technique for midsize antennas, FFT for antennas requiring many wavelengths or, in special cases, such as reflector antennas, the combination of physical optics with MOM maybe preferable.
