In most naturally occurring media, the phase function is a 1D function of the angle θ between the two directions ωo and ωi; these phase functions are often written as p(cos θ). Media with this type of phase function are called isotropic because their response to incident illumination is...
The phase-lag compensator has a negative phase angle and so is used to subtract phase from an uncompensated system. A phase-lag compensator has a transfer function of the form: G(s)=1+τs1+aτs where a is greater than 1. Figure 11.35 shows the type of circuit that can be used (a...

Figure 5. Phase and amplitude response of a 2-pole low-pass filter section as a function ofQ. Note that each 2-pole section provides a maximum 180° of phase shift; and at the extremities, a phase shift of –180°, though lagging by 360°, is an angle with the same properties as ...
The phase angle varies almost linearly as function of tap position as shown on the figure below. Variation of Phase Shift as Function of Tap Position You control tap positions, and therefore phase shift, by sending pulses to one of the two block inputs labeled Up and Do...
Starting from the TNR, one can choose optimal values of the guard angle and the number of quantisation sectors, in order to achieve the maximum number of extractable bits through phase-shift-keying (PSK) demodulation. One of the firsts attempts to exploit frequency diversity was done in ...
On the other hand, Brewster angle microscopy (BAM), a space-resolved imaging ellipsometric technique, was adapted to visualize lateral domain structures in monolayers of amphiphiles adsorbed at an oil/water interface. Although BAM had been used successfully to study monolayer films of amphiphilic ...
