PLANT IMMUNE RESPONSES "lead collectively to pattern-triggered immunity (PTI). To overcome PTI, phytopathogens secrete effector proteins that interfere with plant innate immunity at several levels. If the plant immune response is successfully suppressed by effector proteins, disease occurs." https://lnkd.in/eWZ-igq View in LinkedIn

NEW SYMMETRY. "New physical properties are characterized by breaks in physical symmetry. If you rotate a sphere around its axis it looks the same at every point of rotation -- but if you rotate a cube in this way, it looks the same every 90 degrees of rotation. Therefore, a cube breaks continuous rotation symmetry." https://lnkd.in/eNQRPTA View in LinkedIn

BROKEN SYMMETRY. "In principle, metamaterials can provide large anisotropy and extreme constitutive parameters, with either very small, or very large values." https://lnkd.in/eV48D4C View in LinkedIn

BROKEN SYMMETRY. "Essentially, inhomogeneity and anisotropy in the background plays the role of a geometrical distortion, leading to a practical way to effectively create any coordinate transformation in the physical space, providing one possesses full control over (two parameters)." https://lnkd.in/eV48D4C View in LinkedIn

THE CHALLENGE. "It's not yet clear that you're going to get the invisibility that everyone thinks about with Star Trek cloaking device or the Harry Potter's cloak. To make an object literally vanish before a person's eyes, a cloak would have to simultaneously interact with all of the wavelengths, or colors, that make up light." https://lnkd.in/eGNGas7 View in LinkedIn

EM INVISIBILITY. "Strictly speaking, the invisibility of the object is the absence of electromagnetic field perturbations around the object at large enough distances from it." https://lnkd.in/enxaHbT View in LinkedIn

REALITY CHECK. "The invisibility cloak does not make the object disappear, but guides the light around the hidden object and makes it appear on the other side without deflection, which makes the hidden object undetectable." https://lnkd.in/eyP6_vj View in LinkedIn

INVISIBILITY. "In practical terms, invisibility, or the cloaking effect, aims at cancelling the electromagnetic field that is scattered by an object, by placing it inside a cover (cloak) that makes the ensemble undetectable to electromagnetic sensors." https://lnkd.in/eV48D4C View in LinkedIn

INVISIBILITY. "Perhaps one of the most appealing applications of metamaterials consists in the possibility of making objects invisible to the impinging radiation." https://lnkd.in/eV48D4C View in LinkedIn

EXOTIC POSSIBILITIES. "Metamaterials are well known today for opening exotic possibilities to manipulate electromagnetic waves, including negative refraction, spatial localization and sub-wavelength focusing, spontaneous emission control, and anomalous tunneling effects." https://lnkd.in/eV48D4C View in LinkedIn
