Sources

There are several different types of sources available in EMA3D®. Some are spatially extended sources while others are localized. An extended source is one that is defined to exist within a volume and is implemented using an equivalent surface that encompasses the volume. A localized source is one that is defined to exist at a single location or at many individual locations.

The extended sources are:

The Plane Wave Source,

The Box In Source,

The Box Out Source, and

The Gamma Source.

The localized sources are:

Electric Current Density Source, Magnetic Current Density Source, Electric Field Source, Magnetic Field Source, Thin Wire Current Source, Thin Wire Voltage Source, Cylindrical Conductor Current Source, Cylindrical Conductor Voltage Source.

The specialty sources are:

Capacitor Bank Source

Each of these source types are discussed in separate sections below. Extended sources are discussed in Section 5.6.1. Localized sources are discussed in Section 5.6.2. Specialty sources are discussed in Section 5.6.3. Only the first four localized sources are discussed below. The localized sources for the thin wires and the cylindrical conductors are defined in Section 5.8.1 and Section 5.8.2.

The source waveforms for all localized sources, and for the plane wave source, can be defined using a source data file or a predetermined analytic waveform. The various analytic waveforms are discussed in Section 5.6.4.
