AUTHOR. “Henrik Zinkernagel has a degree in theoretical physics and a doctorate in philosophy of science. He is a full professor in the Department of Philosophy at the University of Granada.” https://lnkd.in/emyq2BPE View in LinkedIn

FRAGMENT FROM NATURE focuses on a consideration of some of the ideas of the famous quantum physicist Niels Bohr, titled Are we living in a quantum world? Bohr and quantum fundamentalism. Bohr was a Danish physicist “who made foundational contributions to understanding atomic structure and quantum theory, for which he received the Nobel Prize in Physics in 1922. Bohr was also a philosopher and a promoter of scientific research.” A remarkable thinker by any standards. https://en.m.wikipedia.org/wiki/Niels_Bohr View in LinkedIn

PROGRAMMABLE FOODS. “Here, we devise meta-atoms with tailored fracture properties to control mouthfeel sensory experience.” https://lnkd.in/eD7iFAGi 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

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
