Hello Everyone: I am designing an EM model in a CST microwave studio with an antenna and metal plate. The excitation to the antenna is the default continuous wave packet. Is there any way I can define a static charge ( like 0.1, 0.2, 0.3 C) on the metal plate and run the simulations? ( Simulation figure is attached)

Thank you,

Kapil
