  • Publication number: 20220383978
    Abstract: The present disclosure provides a method of generating a new trait converted elite cultivar through a method of breeding. For instance, the method involves the use of parent plants, which are respectively the traited variant of the parents of the non-traited elite cultivar and estimating a minimum population size necessary to generate a progeny plant comprising the desired trait and sharing a sufficiently high identity by descent with the non-traited elite cultivar to ensure replication and equivalency of general performance. The present method may be used to generate an elite cultivar in fewer generations, thereby accelerating new line production, and reducing costs. The present method may also be used to generate non-traited variants of traited lines.

  • Patent number: 11489265
    Abstract: The present invention discloses a reconfigurable wideband phase-switched screen (PSS) based on an artificial magnetic conductor (AMC). Gap capacitance between patches is controlled by changing the capacitance of varactors, so that periodic units have a plurality of continuous frequency points. A phase difference between two adjacent frequency bands is 143°-217°, so that the periodic structure absorbs incident electromagnetic waves in a wide frequency band, and the broadband PSS is implemented with a relative bandwidth of 45.2%. The AMC structure according to the present invention is simple in structure and easy to process, with a thickness less than one twentieth of the working wavelength, and greatly reduces size and costs.
