The vector beam state can be described as the tensor product of these two spaces, combining the two DoFs together for the new state \(\left| {\psi _{{{\mathrm{v}}} \right\rangle = \left| {\psi _{{{\mathrm{o}}} \right\rangle \otimes \left| {\psi _{{{\mathrm{p}}} \righ...

Infrared transition yields as a result of the interaction of the oscillating electric vector of the infrared light with the oscillating dipole moment of the molecule (owing to the molecular vibration). The principle of selecting for infrared transitions - which needs to be followed when infrared ...
intensity. Convergence of light by a convex lens is an intuitive example (Fig.6): the wavefront in front of the convex lens is a plane, whose wavevector is parallel to the direction of propagation. As such, the intensity distribution on different planes is constant; that is, the axial va...
If the electric field vector is confined to oscillate in a plane (e.g. the X–Z plane in Figure 1), the wave is said to be linearly polarized. If the tip of the electric field vector traverses an elliptical path around the direction of propagation, the state of polarization is ...
and the vector potential of the electromagnetic field is denoted by ˆA.A^. This gauge is also called the “momentum gauge”. In an alternative representation, the “multipole representation” or “length gauge”, the interaction is formulated in terms of electric displacement and magnetic fields...
process of the phase profile. For example, high refractive index titanium dioxide (TiO2) material-based metasurfaces can strongly confine the electromagnetic waves, reducing the unwanted zeroth-order beam47. On the other hand, vectorial diffraction theories such as finite-difference time-domain (FDTD...
