EM.Illumina provides three types of sources for the excitation of your physical optics simulation(click on each type to learn more about it):

=== Hertzian Dipole Sources === A short Hertzian dipole is the simplest way of exciting a structure in EM.Illumina. A short dipole source acts like an infinitesimally small ideal current source. The total radiated power by your dipole source is calculated and displayed in Watts in its property dialog. [[Image:Info_icon.png|40px]] Click here to learn more about '''[[Common_Excitation_Source_Types_in_EM.Cube#Hertzian_Dipole_Sources | Hertzian Dipole Sources]]'''. === Plane Wave Sources === Your physical structure in EM.Illumina can also be excited by an incident plane wave. In particular, you need a plane wave source to compute the radar cross section of a target. The direction of incidence is defined by the θ and φ angles of the unit propagation vector in the spherical coordinate system. The default values of the incidence angles are θ = 180° and φ = 0° corresponding to a normally incident plane wave propagating along the -Z direction with a +X-polarized E-vector. EM.Illumina provides Huygens sources are virtual equivalent sources that capture the following polarization options: TMz, TEz, Custom Linear, LCPz radiated electric and RCPz. magnetic fields from another structure that was previously analyzed in another [[Image:Info_icon.png|40px]] Click here to learn more about '''[[Common_Excitation_Source_Types_in_EMEM.Cube#Plane_Wave_Sources | Plane Wave Sources]]'''computational module.
