Hello I want to use COMSOL to simulate the response of pyroelectric detector with electromagnetic heating. By using the RF module and solid heat transfer module of COMSOL, I got the results of electromagnetic heating. However, it is learned from subsequent papers that the detection response of pyroelectricity is obtained in periodic irradiation or pulse irradiation. One paper mentioned: the electromagnetic simulations were then coupled into a soildstate heat transfer simulation, where the heat source is spatially defined by the absorber power density and temporally defined by a 100 fs FWHM Gaussian pulse. That is, the energy distribution generated by RF is used as the spatial input of solid heat transfer analysis, and it is a pulse in time. I really don't know how to realize this time control (100 femtosecond Gaussian pulse). I hope you can give me some advice!
