This study focuses on the control of Fano resonance in the elastic plate, which is initially developed in atomic scattering and has been seldom to discuss. Fano resonance is a phenomena involved by the localized/quasi-localized wave, in which the resonance curve becomes asymmetric due to the phase difference between the incident wave and the localized wave. The typical resonance curve available in the system is the frequency dependence of the reflectance under the scattering problem. We will demonstrate that the controllability of the resonance curve using various shapes of the scattering region under the simulation and experiment. The experiment system is an elastic waveguide made of aluminium plate and the scattering region is formed by modulating the plate thickness. The localized wave is induced by incident wave in the thinned scattering region and causes the wave tail that penetrates into the lead region of waveguide. The controllability can be realized by the overlap of the wave tail and the incident wave. For analyzing the experiment data, we also develop the method to extract S-parameters. The controllability was already confirmed by the preliminary experiment. Now, we are preparing verify various shapes of the scattering region for detail experiments.
