BROKEN SYMMETRY. “A remarkable set of experiments led to the conclusion that the four-fold symmetry of the tetragonal basal plane is broken and that the HO is hence a “nematic” phase.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

METAMATERIALS. “The term "programmable matter" was coined in 1991, and we've been fascinated by the concept ever since. The eventual goal is to have microscopic machines that can rearrange their grouping, allowing them to take any form of our choosing."If I have a clump of clay made of thousands of millions of little dots, I push a button then the charges rearrange themselves to form a statue, a car, whatever you want". (Michio Kaku). https://lnkd.in/eXDXhP6Q View in LinkedIn

HIDDEN ORDER. “The mysterious hidden order (HO) phase of the heavy-Fermion URu2Si2 has drawn much attention in condensed matter physics during the last three decades.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

CORE COMPONENT. “Their optical properties are strongly governed by the response of meta-atoms – their elementary units.” https://lnkd.in/e5fJZNfb View in LinkedIn

NANOPHOTONICS. “Metasurfaces, metamaterials, and nanoantennas are the main building blocks of nanophotonics allowing giant field enhancement and precise control over light at the subwavelength scale.” https://lnkd.in/e5fJZNfb View in LinkedIn

SYMMETRY CAUSE. “We demonstrate that bianisotropy is exclusively caused by the absence of the inversion symmetry of metaatoms. The strength of the bianisotropy response is normally increased with the size of a meta-atom but its origin is fully connected to the symmetry of the structure.” https://lnkd.in/e5fJZNfb View in LinkedIn

TWIST EFFECT. “Bi-isotropic materials have the special optical property that they can rotate the polarization of light in either refraction or transmission. This does not mean all materials with twist effect fall in the bi-isotropic class. The twist effect of the class of bi-isotropic materials is caused by the chirality and non-reciprocity of the structure of the media, in which the electric and magnetic field of an electromagnetic wave (or simply, light) interact in an unusual way.” https://lnkd.in/e6TzJnyr View in LinkedIn

FUNCTIONAL DEFINITION. “Bianisotropic materials acquire magnetic (electric) polarization when excited by electric (magnetic) external field.” https://lnkd.in/eHqsJecp View in LinkedIn

ELECTRIC + MAGNETIC FIELDS. “Bianisotropy of metaatoms is usually associated with their nonlocal response and the mutual coupling between electric and magnetic dipole moments induced by the incident field.” https://lnkd.in/e5fJZNfb View in LinkedIn

COUPLED FIELDS. “The electric and magnetic dipole moments (p and m) of meta-atoms are not always independent. They can be mutually coupled, i.e. the both components of incident electromagnetic field (E and H) simultaneously induce p and m. This effect is usually called bianisotropy (BA).” https://lnkd.in/e5fJZNfb View in LinkedIn
