“…In a serial of theoretical works by Tamir [13,17], the relationship between the GH shift and the leaky mode of multilayer and periodic structures are studied. Experimental works demonstrating his theory were carried out much more recently, but mostly on acoustic waves [18][19][20].…”

Giant positive and negative Goos-Hänchen shift more than 5000 times of the operating wavelength is observed when a beam is totally reflected from a substrate decorated by a dielectric grating. Different to the former studies where Goos-Hänchen shift is related to metamaterials or plasmonic materials with ohmic loss, here the giant shift is realized with unity reflectance without the loss. This is extremely advantageous for sensor applications. The Goos-Hänchen shift exhibits a strong resonant feature at the frequency of guided mode resonance, and is associated to the energy flow carried by the guided mode.

“…Diffraction of an acoustic beam from a periodically corrugated interface has been studied in several works [21][22][23][24][25][26][27]. In this type of diffraction phenomenon, the periodic surface corrugations work as a diffraction grating, and the periodicity of the corrugated surface is crucial to the diffraction pattern.…”

Due to the specific elastic properties such as high stiffness to mass ratio, regular microstructure materials are widely used in the industry. The need for nondestructive evaluation is ubiquitous to ensure material quality. As an effective nondestructive testing method, ultrasound has great potential in providing an efficient materials characterization. However, contrary to more convenient ultrasound applications, challenges arise when applying ultrasound to 3D bi-material structures due to the coexistence of different phenomena, including diffraction effects caused by the periodicity. Two linear ultrasound methods, namely the Bragg diffraction and the comb filtering effect, are proposed to address this hurdle. The results show that the comb filtering effect effectively characterizes, respectively, the vertical structural quality of the bi-material. Bragg diffraction can also expose structural variations in the horizontal plane.

“…[6][7][8] In this type of diffraction phenomenon, the periodically corrugated surface works as a diffraction grating and the periodicity of the corrugated surface is crucial to the diffraction pattern. When the incident beam impinges the corrugated surface at a specific angle called Bragg angle, a reflected beam is backscattered to the beam source.…”
