It combines experiments, analytical theory, and numerical simulations to explore nanoscale optical phenomena that challenge our conventional understanding, such as negative reflection, anomalous refraction and polariton canalization. These studies have paved the way for practical applications in integrated flat optics, such as planar lenses and resonators for nanoscale light. The thesis also introduces the emerging field of twistoptics, aimed at controlling the propagation of light at the nanoscale by stacking slabs of van der Waals materials at different rotation angles, and introduces innovative approaches to tune polariton properties both passively and actively. In addition to providing a solid foundation for future advancements in planar nano-optical devices and helping lay the fundamentals of light-matter interactions in hyperbolic van der Waals materials, the thesis's didactic approach makes complex phenomena accessible to a broad audience. 0aNanophotonics.972056 0aPlasmonics.972057 0aOptical materials. 0aCondensed matter.966773 0aSurfaces (Physics).967538 0aPhotonics.965750 0aOptical engineering.96575114aNanophotonics and Plasmonics.97205824aOptical Materials.24aTwo-dimensional Materials.97161024aSurface and Interface and Thin Film.96753924aPhotonics and Optical Engineering.9657532 aSpringerLink (Online service)0 tSpringer Nature eBook08iPrinted edition:z978303175766208iPrinted edition:z978303175768608iPrinted edition:z9783031757693 0aSpringer Theses, Recognizing Outstanding Ph.D. Research,x2190-506196637040uhttps://doi.org/10.1007/978-3-031-75767-9  aZDB-2-PHA  aZDB-2-SXP  c64999d64999
