===Defining Lumped Loads===
In [[EM.Tempo]] you can define four lumped load typesof lumped loads:
# '''Resistor''' with a Resistance value (R) in Ohms.# '''Capacitor''' with a Capacitance value (C) in pF.# '''Inductor''' with an Inductance value (L) in nH. # '''Nonlinear Diode''' with a Saturation Current (I<sub>s</sub>)in fA, ambient temperature (T) in degree Kelvin, and a dimensionless ideality factor (n). The default values of these [[parameters]] are 100fA, 300°K and 1, respectively.
Although lumped loads are not sources and do not excite a structure, their properties are similar to lumped sources. Lumped Loads are incorporated into the FDTD grid across two adjacent nodes in a similar manner to lumped sources. Likewise, lumped loads are defined on Line objects. In order to create a lumped load, you must have at least one line object in your project. Lumped loads show up as small yellow arrows on their host line object. Similar to lumped a source, a lumped load has an offset parameter that determines its location on the host line.
