  text: An approach for the non-destructive characterisation of adhesive bonds using
    guided ultrasonic waves is presented. Pulsed laser radiation is used to thermoacoustically
    excite broadband ultrasonic waves in a multi-layered sample, consisting of a metal
    plate adhesively joined to a polymeric layer using synthetic resin. The resulting
    signals are received by a purpose-built piezoelectric transducer. Varying the
    distance between excitation and detection yields spatio-temporal measurement data,
    from which the dispersive properties of the propagating waves can be inferred
    using a two-dimensional Fourier transform, assuming the plates to act as coupled
    waveguides. Coupled multi-layered waveguides show an effect referred to as <jats:italic>mode
    repulsion</jats:italic>, where the distance between certain modes in the frequency-wavenumber
    domain is assumed to be a measure of coupling strength. Measurements at different
    stages of curing of the adhesive layer are performed and evaluated. A comparison
    of the results shows changes in the dispersive properties, namely an increased
    modal bandwidth for the fully cured sample as well as an increased modal distance.
