A waveguide is a structure that is used to guide electromagnetic waves such as radio waves and microwaves. It serves to channel radio waves in a specific dimension and in a specific shape, allowing them to travel longer distances from the source toward the antenna and to travel only in a pr...

He says the best time to listen for them is around sunset or sunrise. 他说听它们最好的时间是日出或日落的时候。 That's when there're natural waveguides in the local atmosphere. 那时,当地大气中存在着天然波导 Student: Did you say waveguide? 学生:你是说波导吗? Professor: Yes, a waveguide....
waveguide is an integer multiple of the central wavelength of the DeMUX. The wavelengths arrive at the other end of the FPR at slightly offset times, with the signals from the inner waveguide coming last and the outer waveguide arriving last. The lengths of the array waveguides are chosen ...
An arrayed waveguide grating is used in fiber optic transmission systems to permit a single optical fiber to carry multiple channels or communication bands. Fiber optic cables use very thin glass fibers to transmit light signals containing voice or data communications. In the late 20th century, ...

A Process Design Kit (PDK) is a library of basic photonic components generated by the foundry to give open access to their generic process for fabrication.
A ground wave radio signal is made up from a number of constituents. If the antennas are in the line of sight then there will be a direct wave as well as a reflected signal. As the names suggest the direct signal is one that travels directly between the two antenna and is not ...
