Stellarator symmetry is a property of typical stellarator magnetic configurations. In a cylindrical coordinate system, it is expressed as follows for a scalar field:
with respect to the symmetry plane φ = 0. Likewise, for a vector field:
With N-fold rotation symmetry around the Z axis, there are 2N such planes. [1]
