Time domain responses captured along a line of receivers placed at 𝑦=0.50 m, assuming the waveguide with a seabed allowing a dilatational wave velocity of 𝛼_𝑓2=2100.0m/s: (a) without any shell structures; (b) with the two buried shell structures, filled with water; (c) with the two buried shell structures, filled with air; (d) with two buried rigid inclusions.
