When one waveform is displaced in space or time from another with the same period or a harmonic multiple of it, there is said to be a phase difference between them, usually expressed in degrees. For ...

Phase engineering of a wave function influences and determines the tendency and even results of physical processes, especially for efficient nonlinear optical frequency conversion. High conversion ...

As the number of higher-throughput applications grows, so does the need for a wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication ...
