Trigonometric functions have distinct cycles, or "phases"; think of first period of the basic sine wave. A phase shift means nothing more than shifting a given trig function to the left or right, so that the cycle starts at a non-regular point; in other words, that the graph has been ...
For phase-shifting micro lithography, a method of assigning phase to a set of shifter polygons in a mask layer separated by a set of target features includes assigning a first phase to a first shifter polygon, identifying a set of target features that touch the first shifter polygon, and ...

We can have all of them in one equation:y = A sin(B(x + C)) + Damplitude is A period is 2π/B phase shift is C (positive is to the left) vertical shift is DAnd here is how it looks on a graph:Note that we are using radians here, not degrees, and there are 2π ...
New graph bipartizations for double-exposure, bright field alternating phase-shift mask layout We describe new graph bipartization algorithms for lay-out modification and phase assignment of bright-field alternating phase-shifting masks (AltPSM) [25]... AB Kahng,S Vaya,A Zelikovsky - Asp-dac...
However, if the phase retardation introduced by the specimen is large enough (e.g., a phase shift of the diffracted wave by approximately a half wavelength, instead of a quarter wavelength), interference between the diffracted waves and the surround waves can become constructive, making these ...
Learn how to graph tangent functions. Discover the properties of a tangent graph and interpret phase shift and period transformations algebraically...
Therefore, the main solutions of filters that can be used in RCs are either zero-phase or linear-phase low-pass filters. However, when using a linear-phase filter, a phase shift compensation must be carried out. Since RC-based controllers are based on periodic signal generators, they are ...
The system is controlled by a PWM and phase shift control circuit; the overall efficiency of this system is only 93.3%. A modified z-source dual input DC/DC converter is proposed in [15]. The principle of this method is to optimize the power loss by reducing the number of switches ...
