1996 IEEE MTT-S International Microwave Symposium Digest, 2002
Harmonic balance has established itself as an important technique for simulating high frequency circuits. However, this simulator struggles on strongly nonlinear circuits, particularly if there are several input signals at different frequencies. An important observation is that multi-tone nonlinear circuits usually react in a strongly nonlinear fashion

IEEE Microwave and Wireless Components Letters, 2003
This letter introduces a new approach to steady state analysis of nonlinear microwave circuits under periodic excitation. The new method is similar to the well known technique of Harmonic Balance, but uses wavelets as basis functions instead of Fourier series.

Harmonic Balance developments in OpenFOAM
Computers & Fluids, 2018The Harmonic Balance method for simulating unsteady nonlinear periodic flows is presented in this pa- per. Its recent, yet rapid development was motivated by the possibility of significant CPU time consump- tion savings compared to conventional transient methods, while providing sufficient accuracy.

The harmonic balance method is a version of Galerkin’s weighted residual method. The harmonic balance is to seek an approximate periodic solution of a differential-algebraic equation by a truncated Fourier series. Substituting a guessed periodic solution into the differential equation leads to a residual term.

Proceedings of CICC 97 - Custom Integrated Circuits Conference, 2002
Fast and accurate computation of the steady-state response of large nonlinear networks under periodic and quasi-periodic drive is a key simulation problem for integrated RF designs. In this paper we describe recent work which extends the method of Harmonic Balance to networks containing several million unknowns. A new implementation is described, which

Matrix-implicit Krylov-subspace methods have made it possible to efficiently compute the periodic steady-state of large circuits using either the time-domain shooting-Newton method or the frequency-domain harmonic balance method. However, the harmonic balance methods are not so efficient at computing steady-state solutions with rapid transitions, and ...

This chapter describes practical algorithms for implementing harmonic balance. Most of these algorithms have been implemented and tested in Spectre, a simulation program suitable for analog and microwave circuits. There are two fundamental ideas presented in this chapter.
