Spectral Anisotropy in Transition Radiation from Biaxial Media
Sven Ebel, Bibi Mary Francis, Min Seok Jang +4
In anisotropic optical media, the electromagnetic response depends on the orientation of the optical field relative to the material's principal dielectric axes. While this directio…
Local control and lateral nanofocusing of hyperbolic phonon polaritons
Jacob T. Heiden, Haozhe Tong, Yongjun Lim +6
Phonon polaritons in van der Waals crystals enable exceptional light confinement and control over low-loss nanolight propagation. The polariton wavelength can be controlled by the…
Bloch phonon-polaritons with anomalous dispersion in polaritonic Fourier crystals
Sergey G. Menabde, Yongjun Lim, Alexey Y. Nikitin +5
The recently suggested concept of a polaritonic Fourier crystal (PFC) is based on a harmonically-corrugated mirror substrate for a thin pristine polaritonic crystal layer. The prop…
Prospects to bypass nonlocal phenomena in metals using phonon-polaritons
Jacob T. Heiden, Eduardo J. C. Dias, Minhyuk Kim +6
Electromagnetic design relies on an accurate understanding of light-matter interactions, yet often overlooks electronic length scales. Under extreme confinement, this omission can…
Polaritonic Fourier crystal
Sergey G. Menabde, Yongjun Lim, Kirill Voronin +4
Polaritonic crystals - periodic structures where the hybrid light-matter waves called polaritons can form Bloch states - promise a deeply subdiffractional nanolight manipulation an…
