Optimization Approaches in Sideband Calculations and a Non- Iterative Harmonic Suppression Strategy in 4D Arrays

In this chapter, the harmonic calculations and suppression methods in 4D arrays are explored. First, the fundamentals of the 4D arrays including the switching strategies and metaheuristic approach to suppression of sidebands are provided, and further, the har- monic reduction strategies using optimizers are discussed. Finally, a novel noniterative algorithmic way to suppress the harmonic radiations is introduced and exemplified by an illustrative example.
