Bound States in the Continuum - Massachusetts Institute of ...

The waveguide supports a continuum of waves propagating in x that are either even or odd under mirror reflection in y; the odd ones (shown in orange) require at least one oscillation in y and only exist above a cutoff frequency (πc s/h), where c s is the sound speed and h is the width of waveguide. Since the plate respects the
