Query: Topologically protected edge modes in one-dimensional chains of
  subwavelength resonators   The goal of this paper is to advance the development of wave-guiding
subwavelength crystals by developing designs whose properties are stable with
respect to imperfections in their construction. In particular, we make use of a
locally resonant subwavelength structure, composed of a chain of high-contrast
resonators, to trap waves at deep subwavelength scales. We first study an
infinite chain of subwavelength resonator dimers and define topological
quantities that capture the structure's wave transmission properties. Using
this for guidance, we design a finite crystal that is shown to have wave
localization properties, at subwavelength scales, that are robust with respect
to random imperfections.
