Hybrid topological guiding mechanisms for photonic crystal fibers
Mehul P. Makwana, Richard Wiltshaw, Sébastien Guenneau +1
We create hybrid topological-photonic localisation of light by introducing concepts from the field of topological matter to that of photonic crystal fiber arrays. S-polarized obliq…
Ultra-thin, entirely flat, Umklapp lenses
Gregory J. Chaplain, Richard V. Craster
We design ultra-thin, entirely flat, dielectric lenses using crystal momentum transfer, so-called Umklapp processes, achieving the required wave control for a new mechanism of flat…
Fresnel drag in space-time modulated metamaterials
P. A. Huidobro, E. Galiffi, S. Guenneau +2
A moving medium drags light along with it as measured by Fizeau and explained by Einstein's theory of special relativity. Here we show that the same effect can be obtained in a sit…
Novel topological beam-splitting in photonic crystals
Mehul P. Makwana, Richard Craster, Sebastien Guenneau
We create a passive wave splitter, created purely by geometry, to engineer three-way beam splitting in electromagnetism in transverse electric polarisation. We do so by considering…
Extraordinarily transparent compact metallic metamaterials
Samuel J. Palmer, Xiaofei Xiao, Nicolas Pazos-Perez +5
Metals are highly opaque, yet we show that densely packed arrays of metallic nanoparticles can be more transparent to infrared radiation than dielectrics such as germanium, even fo…
Asymptotic network models of subwavelength metamaterials formed by closely packed photonic and phononic crystals
Alice L. Vanel, Ory Schnitzer, Richard V. Craster
We demonstrate that photonic and phononic crystals consisting of closely spaced inclusions constitute a versatile class of subwavelength metamaterials. Intuitively, the voids and n…
