We numerically show that hyperlens-based nanofocusing device can compress a Gaussian beam down to tens-of-nanometers of spot size in the ultraviolet (UV) and visible frequency range. We also report four types of hyperlenses using different material combinations to span the entire range of visible...
To solve the question, we need to analyze the conditions under which all wavelengths of light are scattered nearly equally by an object of size
Inwirelesssystems, wavelength is usually specified in meters (m), centimeters (cm) or millimeters (mm). In the case of infrared (IR), visible light, ultraviolet (UV) and gamma radiation (γ), the wavelength is more often specified in nanometers (nm) or angstroms (Å). Nanometers are ...

An ultraviolet (UV) or visible (VIS) light source is critical for SLA printing technology. UV light can be used to manufacture 3D objects in SLA-3DP, but there are significant occupational safety and health issues (particularly for eyes). These issues prevent the widespread use of SLA-3DP ...
11、This is because thewavelengthof visible light is longer than 200 nanometres.(因为可见光的波长大于200纳米。) 12、The assumption of constant relative humidity is important, because water vapor in the atmosphere is another efficient absorber of radiation at infraredwavelength.(相对湿度恒定的假设是重...
