uniform plane wave वाक्य

These uniform plane waves form the basis for understanding Fourier optics.
which represents a propagating or exponentially decaying uniform plane wave solution to the homogeneous wave equation.
From this equation, we'll show how infinite uniform plane waves comprise one field solution ( out of many possible ) in free space.
Physically, this represents a uniform plane wave propagating in the plane of the FSS . In the spatial domain, the coherent summation of all of the spatial domain Green's function's becomes infinite, so that any finite current produces an infinite field on the surface of the FSS . As a result, all currents must be zero under this condition.
It is of course, very tempting to think that if a plane wave emanating from the finite aperture of the transparency is tilted too far from horizontal, it will somehow " miss " the lens altogether but again, since the uniform plane wave extends infinitely far in all directions in the transverse ( " x "-" y " ) plane, the planar wave components cannot miss the lens.
