Query: Magnonic band gaps in YIG based magnonic crystals: array of grooves
  versus array of metallic stripes   The magnonic band gaps of the two types of planar one-dimensional magnonic
crystals comprised of the periodic array of the metallic stripes on yttrium
iron garnet (YIG) film and YIG film with an array of grooves was analyzed
experimentally and theoretically. In such periodic magnetic structures the
propagating magnetostatic surface spin waves were excited and detected by
microstripe transducers with vector network analyzer and by Brillouin light
scattering spectroscopy. Properties of the magnonic band gaps were explained
with the help of the finite element calculations. The important influence of
the nonreciprocal properties of the spin wave dispersion induced by metallic
stripes on the magnonic band gap width and its dependence on the external
magnetic field has been shown. The usefulness of both types of the magnonic
crystals for potential applications and possibility for miniaturization are
discussed.
