The effect of destructive interference between the direct and the reflected sound waves at the microphone is not considered in this work because the unvested frequencies are considered destroyed.
In the branching measurements, it seems, waves bouncing back to the channel were interfering with other waves, creating patterns of crests and troughs from constructive and destructive interference.
Instead, the optical pattern in the far-field is characterized by the diffraction orders that result from the constructive and destructive interference of all of the light waves that emerge, each from a different aperture of the grating.
The relative amplitudes of, and constructive and destructive interference effects among the signals radiated by the individual antennas determine the radiation pattern of the array.
Flex is best known for its colour shifting interference pigment products which create colour-change functions through constructive and destructive interference between the layers of the coating (compared to the more usual diffractive functioning of DOVIDs).
Dicke, 31 there is a preference for constructive interference (super-radiance) in the initial phase of the interaction between radiation and non-randomly oriented matter of suitable size, while destructive interference (subradiance) dominates after longer periods of time.
Sound waves are also influenced by destructive interference.
Electrons diffuse in the direction of the concentration gradient and drift (due to the photo voltaic effect) to the regions of destructive interference where they relax to empty states in the energy-band gap.
Depending on the thickness of the layers, constructive or destructive interference occurs.
