摘要
A layered structure (100) for transmission of an acoustic wave, the layered structure (100) comprising: a substrate layer (102); and a second layer (104) over the substrate layer (102), wherein the second layer (104) comprises a plurality of discrete portions (105) adjacent to each other, each discrete portion (105) of the plurality of discrete portions (105) comprising a first subregion (104A) and a second subregion (104B). Also an epitaxial layer (108), grown over the second layer (104), for transmission of the acoustic wave in a major plane of the epitaxial layer (108), wherein a periodicity (λ) of a wavelength of the acoustic wave to be transmitted through the epitaxial layer (108) is approximately equal to a sum of a width (dA) of the first subregion (104A) and a width (dB) of the second subregion (104B).
