... the symmetric Lamb modes bandgap can be established in a wide frequency range. Afterwards, an elastic wave diode is constructed by combining the proposed unit cells for the nonreciprocal transmission manipulation of symmetric Lamb waves. The proposed nonreciprocal transmission capability may possess great...
