We show that a plane wave with orthogonal phase velocity cannot possess linear momentum. Moreover, we show that a plane wave without the linear momentum cannot propagate at all, so the orthogonality of the phase velocity does not take place in reality for electromagnetic plane waves....

where\(P({\bf{u}})=|P({\bf{u}})|{e}^{ikW({\bf{u}})}\)is the coherent transfer function with the pupil function\(|P({\bf{u}})|\)(in the most case is a circ-function) and the wave-front aberration\(W({\bf{u}})\). Due to superposition of intensities, the observed ...
Such a state corresponds to an inclined plane wave incident on an object placed in the far-field of the crystal. Such wave planes are exactly the illumination that is needed to perform a Fourier ptychographic (FP) reconstruction. By illuminating an object with an SPDC signal beam and detectin...
The present article is concerned with the propagation of plane waves in a homogeneous, fiber-reinforced orthotropic thermoelastic rotating half-space in the context of three-phase-lag model. There exist three coupled waves, namely, quasi-longitudinal P-wave (qP), quasi-longitudinal thermal wave (qT...
There may be a hexatic smectic B phase having short-range positional order combined with long-range bond-orientational order in the plane of the layers. II.A.2.c Smectic C The smectic C phase (Fig. 3) is similar to the smectic A phase except that the director makes an angle, called ...
One particular feature of a converging wave travelling through its focus is the acquisition of an additional phase shift when compared with a collimated beam or a plane wave travelling the same distance. This effect, which is known as the Gouy phase, was first observed and described by Gouy ...
Wave modulating is one of the most interesting applications of metasurfaces. It requires an effective method to design metasurfaces with arbitrary space-variant phase. In this paper, we proposed an optimized design method for arbitrarily modulating wave based on the Genetic Algorithm, which is effici...
