[EN] High-index dielectric disks with subwavelength
dimensions seem relatively simple electromagnetic structures.
However, they can give rise to exotic phenomena in
nanophotonics. Here we show recent findings that show ...

[EN] Anapole states¿characterized by a strong suppression of far-field scattering¿naturally arise in high-index nanoparticles as a result of the interference between certain multipolar moments. Recently, the first-order ...

[ES] Las nanopartículas de alto índice admiten multipolos electromagnéticos que determinan su respuesta a una onda incidente. Cuando se excitan diferentes multipolos, estos pueden interferir, dando lugar a fenómenos ...
[EN] It has been shown that the photonic bandgap of one-dimensional (1D) dielectric periodic thin films can vanish at the first Bragg condition for TM modes. Here, we address the case of 1D photonic crystal slabs formed ...
