DESCRIPTION:We perform non-linear simulations of ultra-compact spacetimes 
 with a light ring and an object with a surface that reflects scalar and/or
  gravitational fields.The object&#x27\;s material is unknown\, but replace
 d by reflecting boundary\, whose location can be freely chosen. We investi
 gate the dependence of the emitted waveforms on the position of the surfac
 e and compare to the non-reflecting case. In the waveforms we are looking 
 on features that are conjectured for some horizonless ultracompact objects
 \, such as echoing signals and a cascade to higher multipoles
