Problems solved by technology

[0004] Various structural tube materials in the prior art cannot meet the application in a wide range of fields. The hollow waveguide has problems such as low bonding force between the plastic tube and the metal reflective layer, poor temperature resistance and bending resistance of the waveguide. , which greatly limits the development of flexible hollow-core waveguides based on plastic structural tubes
Little research has been done on flexible waveguides capable of operating in hot and cold environments
