Abstract: Despite the complexity of non-axisymmetric geometries, the advent of optimized configurations has allowed stellarator research to remain relevant in the modern field of plasma fusion research. Development of reactor scale optimization schemes continues to progress rapidly with support from ongoing experiments at devices around the world. The most prominent configurations discussed in the field today are the quasi-isodynamic, quasi-helically symmetric, and quasi-axisymmetric configurations. Additional cases, such as the piecewise omnigenous configuration, promote continued research on existing devices that were not designed with modern optimization techniques. Mature areas of research in axisymmetric configurations, such as fast ions and Alfven eigenmodes, will have a lot to offer for comparison as the gap between stellarator and tokamak research narrows.
