“…For example, a simple planar periodic array of split-ring resonators (SRRs) provides magnetic resonances. Of particular interest is a stacked SRR dimer, in which the relative twist angle between the dimer constituents tunes the degree of interference between the electric and magnetic modes [6,10–11]. This varied interference turns out to be related to the co- and counter-rotations under current investigation as presented in Fig.…”

SummaryThis study is motivated in part to better understand multiplexing in wireless communications, which employs photons carrying varying angular momenta. In particular, we examine both transverse electric (TE) and transverse magnetic (TM) waves in either co-rotations or counter-rotations. To this goal, we analyze both Poynting-vector flows and orbital and spin parts of the energy flow density for the combined fields. Consequently, we find not only enhancements but also cancellations between the two modes. To our surprise, the photon spins in the azimuthal direction exhibit a complete annihilation for the counter-rotational case even if the intensities of the colliding waves are of different magnitudes. In contrast, the orbital flow density disappears only if the two intensities satisfy a certain ratio. In addition, the concepts of spin sifters and enantiomer sorting are illustrated.
