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

NEW FIELD. “The multipole description has important bearings for the understanding of macroscopic phenomena in magnetic crystals. The new emerging understanding is that the multipole moments pertaining to the magnetic structure characterize magneto-electric phenomena.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

EXOTIC PROPERTIES. “A second conclusion derived from the recent research on magnetic multipoles is that there is a huge potential for novel, exotic phenomena.” https://journals.jps.jp/doi/full/10.7566/JPSJ.87.041008 View in LinkedIn

“MAGNET, n. Something acted upon by magnetism." "MAGNETISM, n. Something acting upon a magnet." "The two definitions immediately foregoing are condensed from the works of one thousand eminent scientists, who have illuminated the subject with a great white light, to the inexpressible advancement of human knowledge.” (Ambrose Bierce, The Devil’s Dictionary). https://lnkd.in/eY_xwJvf View in LinkedIn

DEFINITION. “Multipole moments are the coefficients of a series expansion of a potential due to continuous or discrete sources (e.g., an electric charge distribution). All atoms and molecules (except S-state atoms) have one or more non-vanishing permanent multipole moments.” https://lnkd.in/eZKMH75i View in LinkedIn
