Now a days, plenty of nanostructured absorbers have been designing and investigating by
employing various novel materials. In this paper, we employ a single-layer and ultrathin …

We report on the theoretical, numerical, and experimental investigation of secure acoustic
holography. This secure holography is achieved via an encoded hologram generated by a …

This paper introduces an ultrathin metamaterial absorber based on MXene, consisting of a
subwavelength-sized periodic square-ring-shaped nano-cylinder operating in the visible …

The effective control of low-frequency noise remains a formidable challenge due to the
inherently long wavelengths involved, which typically require large-scale physical barriers to …

Optoacoustic microscopy faces a restricted depth of field attributed to the tightly focused
Gaussian beam excitation. This limitation poses challenges in capturing high-resolution …

Unlocking the full potential of wavefront manipulation and particle trapping with high spatial
precision requires a flexible approach to remotely trigger the desired ultrasonic wave with …

In this work, we propose a deep convolutional attention neural network to realize the
recognition of acoustic vortex fields. Convolutional attention mechanisms are introduced into …

High-resolution ultrasonic imaging, which is highly demanded in nondestructive evaluation,
is inherently limited by the detection wavelength. Acoustic metamaterial is an emerging …

Acoustic radiation forces have been used to trap various objects for fundamental studies and
practical applications. Born approximation method, originally introduced to solve quantum …

Strengthened directivity with higher-order side lobes can be generated by the transducer
with a larger radius at a higher frequency. The multi-annular pressure distributions are …
