Abstract
A novel and useful method of visualization by detection of EM radiation being irradiated or reflected from objects in the imager's field of view using Finite Element Method (FEM) simulation software tools. The methodology provides a verification method of antenna operation from an electrical point of view since bolometer performance cannot be estimated using regular antenna parameters such as directivity, gain, impedance matching, etc. as the bolometer does not behave as an antenna but rather behaves as an absorber. An incident wave is triggered on the absorber and the absorption of the bolometer structure is estimated using commercially available Finite Element Method (FEM) software (e.g., ANSYS® HFSS software, CST MICROWAVE STUDIO®, etc.). How much of the energy is reflected is subsequently measured. The energy which is not reflected is considered to be absorbed by the absorber.
