tidy3d.ModulationSpec

class ModulationSpec

Specification adding space-time modulation to the non-dispersive part of medium including relative permittivity at infinite frequency and electric conductivity.

Parameters:

• permittivity (Attribute: permittivity) –

  Type	Optional[SpaceTimeModulation]
  Default	= None
  Description	Space-time modulation of relative permittivity at infinite frequency applied on top of the base permittivity at infinite frequency.

• conductivity (Attribute: conductivity) –

  Type	Optional[SpaceTimeModulation]
  Default	= None
  Description	Space-time modulation of electric conductivity applied on top of the base conductivity.
