✦ Synopsis

The hydrodynamic transport equations for charges in a semiconductor have been solved for a periodic excitation by means of a harmonic approach, in order to model microwave and millimetre-wave active devices. The solution is based on the expansion of physical variables in a Fourier series in the time domain, and on discretisation in the space domain. A waveform-balance technique in the TD is used to solve the nonlinear equations system. This approach allows for a longer time step with respect to standard TD solutions for most cases of interest, greatly reducing simulation time by at least two orders of magnitude in typical cases.

## Abstract A new method is introduced for solving the sets of discretized non‐linear equations which arise in the modelling of semiconductor microwave devices. The technique involves writing the functions to be solved as the right‐hand sides of damped differential equations. Following the solution
