Summary: Acoustic metasurfaces, with their thin, two-dimensional, and miniature artificial materials that can control sound waves, have great potential in beam-forming acoustic antennas. In this study, we propose an acoustic metasurface that utilizes multi-beam acoustic radiation for acoustic beam steering. By using the holographic principle, a sinusoidal modulated admittance surface is patterned, generating sound surface waves and leaky-wave radiation. Experimental results demonstrate multidirectional acoustic beam steering and forward-backward multibeam frequency scanning. This research holds promise for applications in acoustic communications, levitation, and imaging.

Summary: A four-element leaky-wave antenna array configuration based on a dielectric slab waveguide is presented, with open-stopband suppression, operating in the K-alpha band. A one-to-four power divider using Y-junctions has been developed for the feed network of the antenna array, resulting in a decrease in beamwidth of the radiation pattern in the transverse plane and obtaining a frequency-scanning pencil-beam radiation pattern. The array is placed above a planar metal reflector to increase the radiation gain.

Summary: The friction and wear behaviors between cartilage replacement materials and articular cartilage are crucial for the function and performance of the replacements. This study investigated the difference between cross-shear motion and reciprocal linear motion on the frictional and wear behaviors of cartilage, as well as the effect of bearing surface roughness. The results showed that there was no significant difference between the two motion types. The water contact angle of the bearing surface affected the friction and wear behaviors for low roughness implants, while the surface roughness of the material affected the behaviors for high roughness implants. PEEK was found to be a suitable material for osteochondral implants.
