Unidirectional and topological surface plasmon polaritons are currently attracting substantial interest and intense debate. Realistic material models and energy conservation considerations

are essential to correctly understand extreme wave effects in non-reciprocal plasmonics, and to assess their potential for novel devices. Access through your institution Buy or subscribe
