Unlike in the case where a `SpatialDataArray`, custom doping defined with `CustomDoping` have additive behavior, i.e., one can add other doping on top. This deprecates the `SpatialDataArray` as direct input for `N_a` and `N_d`. - Non-isothermal Charge simulations are now available. One can now run this type of simulations by using the `SteadyChargeDCAnalysis` as the `analysis_spec` of a `HeatChargeSimulation`. This type of simulations couple the heat equation with the drift-diffusion equations which allow to account for self heating behavior. - Because non-isothermal Charge simulations are now supported, new models for the effective density of states and bandgap energy have been introduced. These models are the following: `ConstantEffectiveDOS`, `IsotropicEffectiveDOS`, `MultiValleyEffectiveDOS`, `DualValleyEffectiveDOS`. +- Added `MicrowaveModeSpec` for RF-specific mode information with customizable characteristic impedance calculations through `ImpedanceSpec`. ### Changed - `LayerRefinementSpec` defaults to assuming structures made of different materials are interior-disjoint for more efficient mesh generation. diff --git a/schemas/EMESimulation.json b/schemas/EMESimulation.json index d3a67be719..c44e56c4dd 100644 --- a/schemas/EMESimulation.json +++
