Incoming Wave
The Incoming Wave boundary condition
lets a time-dependent wave Vin enter the domain. The outward-pointing normal n is defined in the section describing the Absorbing Boundary node. The Incoming Wave boundary condition is only available on exterior boundaries.
Voltage
Select a voltage source Type for the input Electric potential Vin (SI unit: V)— Sinusoidal (the default) or User defined.
•
If a Sinusoidal type is selected under Voltage, enter the Frequency f0 (SI unit: Hz) and Amplitude V0 (SI unit: V). The default Frequency is 1 GHz and the default Amplitude is 1 V.
•
If an User defined type is selected under Voltage, enter the expression for the input Electric potential Vin (SI unit: V). The default expression is sin(2πf0t) V where f0 is 1 GHz.
