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

PROGRAMMABLE METAMATERIALS. “In this way, many fascinating effects have already been demonstrated and explained such as non-radiating anapole effect, directional scattering, cloaking and invisibility effects.” https://lnkd.in/e5fJZNfb View in LinkedIn

NANOSCALE PROPERTIES. “As soon as the meta-atoms are usually sufficiently smaller than the wavelength, the scattered field can be well described by only the electric (ED) and magnetic (MD) dipoles that makes it extremely helpful to interpret and predict the optical properties of single meta-atoms and their ensembles.” https://lnkd.in/e5fJZNfb View in LinkedIn

MAGNETIC POLARIZATION. “In the scattered field domain, the meta-atoms can be considered as effective point scatterers with specific polarizabilities corresponding to its dominant multipole moments.” https://lnkd.in/e5fJZNfb 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

PHOTONS + META-ATOMS. “One of the most powerful tool for such an analysis is the multipolar expansion method. Within this method, the electromagnetic field inside and outside the scatterer of an arbitrary shape is described by a superposition of vector spherical harmonics (VSHs) forming a complete set of basis functions known as multipoles.” https://lnkd.in/e5fJZNfb View in LinkedIn

DEFINITION. “Metamaterials are artificial structures with unusual and superior properties that come from their carefully designed building blocks -- also called meta-atoms.” (Programmable matter). https://lnkd.in/eD7iFAGi View in LinkedIn

THE NEED. “The accurate description of light interaction with individual meta-atoms and their small clusters is of high interest to the nanophotonics community as it opens a way for effective engineering the nanophotonic structures with predesigned optical properties.” https://lnkd.in/e5fJZNfb View in LinkedIn

THE THESIS. “I will defend a variant of the traditional reading of Bohr in which (1) the answer to what an object is (quantum or classical) depends on the experimental context; and (2) in principle, any physical system can be treated quantum-mechanically but not all systems can be treated that way at the same time.” https://lnkd.in/eauD5rnp View in LinkedIn

“Snails usually have a spiral-shaped shell which is wound around a spindle. This is the snail shell which they retract their soft bodies into when there is danger. Because of this, they are asymmetrical, and this asymmetry is mirrored inside their bodies. The snail shell is al- ways constructed in the same way. The direction of the spiral is typi- cal for a particular species.” https://lnkd.in/e63P9ske View in LinkedIn
