Plotting the E-Field Magnitude Normal to a Surface

Description

This recipe generates a scalar intensity plot of the E-field magnitude normal to a particular surface (or group of object surfaces, list of object faces), relative to a given input phase excitation. where S is the surface geometry, and is the normal vector to the surface S.

Usage Examples

This calculation could be used instead of the automatic PlotFieldsMagE upon surface, when only the magnitude of the E-field with a particular vector orientation is desired. For example, to evaluate the field available for coupling to a probe structure with a particular orientation.

Prerequisites

You should create the plane to which the desired field component should be normal before you begin the following steps. Use Modeler>Draw>Plane, or Modeler>List>Create>Faces List, or Modeler>Draw>Rectangle (or other 2D sheet).
