Optical metamaterials are an effective way to utilize their superior photon capture capabilities. Therefore, perfect absorbers can be achieved through nanoscale resonant plasmas and metamaterial structures.Metamaterial perfect absorbers (MPAs) are typically composed of periodic subwavelength metals (such as plasma superabsorbers) or dielectric resonance units. Compared with static passive physical...
Professor Zhang Peilei's team from Shanghai University of Engineering and Technology, in collaboration with the research team from Warwick University and Autuch (Shanghai) Laser Technology Co., Ltd., published a review paper titled "A review of ultra shot pulse laser micromachining of wide bandgap semiconductor materials: SiC and GaN" in the international journal Materials Science in Semiconductor...
Researchers have shown that dissipative Kerr solitons (DKS) can be used to create chip based optical frequency combs with sufficient output power for optical atomic clocks and other practical applications. This progress may lead to chip based instruments being able to perform precise measurements that were previously only possible in a few specialized laboratories.Gr é gory Moille from the ...
A group of researchers and companies are using the iLAuNCH Trailblazer program to develop and identify new optical manufacturing processes and materials for space flight applications, and demonstrating them in space cameras.The University of South Australia, together with SMR Australia and VPG Innovation, will utilize an emerging optical manufacturing technology called freeform optics, which is no...
Robotic lawn mowers are becoming increasingly popular due to their convenience and ability to save time and effort. Although robotic lawnmowers have made significant progress over the years, many robots still require users to lay perimeter wires to define the mowing area and remove any obstructions from the lawn to ensure the mower doesn't get stuck or damaged.Well, that's not the case with the Ne...
