abstract = {This  letter  introduces  radial  grooves  as  a  feasi-
ble  geometry  to  support  spoof  surface-plasmon-polariton  (SPP)
waves  propagating  along  a  vacuum-metallic  interface.  Through
the  analytical  derivation  of  a  dispersion  relation,  validated  also
with   full-wave   simulations,   the   ability   of   radial   grooves   to
operate  in  the  fundamental  mode  at  the  microwave  regime  is
demonstrated.  Also,  results  demonstrate  the  utility  of  radial
geometries  to  decrease  the  depth  of  the  grooves,  in  comparison
with  the  widely  used  rectangular  grooves,  thereby  providing  a
superior  methodology  for  generating  spoof  SPPs},
