Arabinda Haldar has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 10186746
    Abstract: A waveguide for spin wave (SW) transmission, a method of fabricating a waveguide for SW transmission, and a method of transmitting an SW. The waveguide comprises a plurality of nanomagnetic material elements, each nanomagnetic material element having a respective predetermined geometric shape such that each nanomagnetic material element exhibits a deterministic ground state initializable by a magnetic field applied across the waveguide; wherein the nanomagnetic material elements are disposed relative to each other for dipolar coupling between adjacent nanomagnetic material elements.
    Type: Grant
    Filed: December 19, 2016
    Date of Patent: January 22, 2019
    Assignee: National University of Singapore
    Inventors: Arabinda Haldar, Dheeraj Kumar, Adekunle Adeyeye
  • Patent number: 9755652
    Abstract: A nanomagnetic structure and a method of fabricating a nanomagnetic structure. The nanomagnetic comprises two or more nanomagnetic material elements, each nanomagnetic material element having a respective predetermined geometric shape such that the nanomagnetic structure exhibits different stable ground states initializable by magnetic fields applied across the nanomagnetic structure in respective different directions; wherein the nanomagnetic material elements are disposed relative to each other such that the magnetic structure exhibits a difference in effective internal magnetic field strength between the different stable ground states. Advantageously, this variation in the internal magnetic field strength is the key for distinct dynamic response associated with the different magnetic ground states. Reconfigurable operation has been shown based on this magnetization dynamics in example embodiments.
