EM.Tempo offers the following types of observable:
* '''[[FDTD_Observable_TypesData_Visualization_and_Processing#Probing_Fields_in_Time_and_Frequency_Domains|Field Probe]]''' for monitoring E- and H-field components at a fixed location in both time and frequency domains. * '''[[FDTD_Observable_TypesData_Visualization_and_Processing#FrequencyVisualizing_3D_Near-Domain_Near_Field_VisualizationField_Maps |Field Sensor]]''' for monitoring E- and H-field components on a cross section of the computational domain in both time and frequency domains.* '''[[FDTD_Observable_TypesData_Visualization_and_Processing#Far_Field_Calculations_in_FDTDVisualizing_3D_Radiation_Patterns |Far-Field Radiation Pattern]]''' for monitoring the radiation behavior of your structure.* '''[[FDTD_Observable_TypesData_Visualization_and_Processing#Radar_Cross_SectionVisualizing_3D_RCS |Far-Field RCS]]''' for monitoring the scattering behavior of your structure.* '''[[FDTD_Observable_Types#Scattering_Parameters_and_Port_Characteristics|Port Definition]]''' for calculating the S/Y/Z [[parameters]] and voltage standing wave ratio (VSWR).
* '''[[#Exciting_Periodic_Structures_Using_Plane_Waves|Periodic Characteristics]]''' for calculating the reflection and transmission coefficients when your periodic structure is excited by a plane wave source.
* '''Domain Energy''' for calculating the total electric and magnetic energy in the computational domain.
