=== Field Sensor ===
Just like other EM.CUBE Modules, EM.Ferma has a standard Field Sensor observable. To specify a Field Sensor, right-click on "Field Sensors" in the navigation tree and click "Add New...". The Field Sensor dialog allows the user to select the direction of the sensor, visualization type, and whether E-field output or H-field output will be shown during a sweep analysis.
In EM.Ferma, Field Sensors are also used to specify 2D solution planes for EM.Ferma's 2D solution mode. This will be detailed shortly.
The E-fields and H-fields are computed at each mesh node within the specified 2D Field Sensor plane. In other words, the resolution of the Field Sensor is controlled by the mesh resolution.
