“…I n connection with this i t seemed probable from the writer's previous work on streptococci (Wright 1925) and from earlier work upon the piieumococcus (Blake 1917, Dochez and Avery 1916) that this would be found most marked in the early hours of growth. Accordingly it is the latent period which has been mainly investigated.…”

“…In contrast to the case of metagratings having a single line current in a super cell [11][12][13], when it comes to greater number of line currents per supercell there are no exact analytical formulas for reactive load impedance densities necessary for obtaining some diffraction pattern. To approach this problem we develop a very simple real valued genetic algorithm [19] which allows one to find reactive Z q with given impedance reactivity accuracy p for a desired diffraction pattern obtained with given transformation accuracy α. The impedance reactivity accuracy is defined in accordance with the following inequality N q=1 |Re[Z q ]/Z q | 2 < p. A diffraction pattern is set by assigning to all α 0 m certain values.…”

Controlling Diffraction Patterns with Metagratings

In this study we elaborate on the recent concept of metagratings proposed in Ra'di et al. [Phys. Rev. Lett. 119, 067404 (2017)] for efficient manipulation of reflected waves. Basically, a metagrating is a set of 1D arrays of polarization line currents which are engineered to cancel scattering in undesirable diffraction orders. We consider a general case of metagratings composed of N polarization electric line currents per supercell. This generalization is a necessary step to totally control diffraction patterns. We show that a metagrating having N equal to the number of plane waves scattered in the far-field can be used for controlling the diffraction pattern. To validate the developed theoretical approach, anomalous and multichannel reflections are demonstrated with 3D full-wave simulations in the microwave regime at 10 GHz. The results can be interesting for the metamaterials community as allow one to significantly decrease the number of used elements and simplify the design of wavefront manipulation devices, what is very convenient for optical and infra-red frequency ranges. Our findings also may serve as a way for development of efficient tunable antennas in the microwave domain.

“…It might have been expected from text-book references to genetic mosaics that the abnormal area would be symme.trical and unitary, though several detailed descriptions of genetic mosaicism have previously demonstrated the inaccuracy ofthis idea. Many coat-colour mosaics in mice, rats, rabbits, and guinea pigs have involved a single patch of abnormally coloured fur (Castle 1922(Castle , 1929Pincus 1929;Fisher 1930;Bittner 1932) but several with more than one abnormally coloured area have been described (Wright and Eaton 1926;Dunn 1934;Feldman 1935). Sturtevant (1929) concluded from his extensive studies of genetic mosaics in Drosophila simulans that the first cleavage patterns are indeterminate since there was no definite pattern among these mosaics.…”
