The default computation frequency of the above observables is the project's center frequency (fc). You can change the observable frequency from the observable's property dialog and enter any frequency in Hz. The reason these types of simulation data are computed at a single frequency is their typically very large size. However, you can define as many instances of these observables and set different frequency values for each one. To facilitate the process of defining multi-frequency observables in EM.Tempo, you can use the following Python functions at the command line:

emag_field_sensor_multi_freq(f1,f2,df,dir_coordinate,x0,y0,z0)
emag_farfield_multi_freq(f1,f2,df,theta_incr,phi_incr)
Â
emag_rcs_bistatic_multi_freq(f1,f2,df,theta_incr,phi_incr)
Â
emag_rcs_monostatic_multi_freq(f1,f2,df,theta_incr,phi_incr)
Â
emag_huygens_surface_multi_freq(f1,f2,df,x1,y1,z1,x2,y2,z2)

In the above functions, f1 and f2 are the start and stop frequencies, respectively, and df is the frequency increment, all expressed in Hz.
