X-ALT-DESC:Description: <br /><p>Online seminar: A universal inverse-design
  magnonic device</p>\n<p>By Prof. Chumak\, Univ. Vienna\, Austria</p>\n<p>
 Magnons\, the quanta of spin waves\, can potentially be used for energy-ef
 ficient data processing. The approach can\, in particular\, leverage the c
 oncept of inverse design\, which involves defining a desired functionality
  and then using a feedback-loop algorithm to optimize device design. Here 
 we report a simulation-free inverse-design device that can implement vario
 us radiofrequency components and can process data in the gigahertz range. 
 The device consists of a square array of independent direct current loops 
 on top of a yttrium iron garnet film that generate a complex reconfigurabl
 e magnetic medium. We use two feedback-loop algorithms&mdash\;direct searc
 h optimization and a genetic algorithm&mdash\;to configure the field patte
 rns and create a linear radiofrequency notch filter and a demultiplexer.</
