Asymmetric optical responses of photonic systems for forward and backward incidences are
of great importance for practical applications. In this work, we theoretically demonstrate …

The interaction between quantum two-level systems is typically short range in free space
and in most photonic environments. We show that diminishing momentum isosurfaces with …

Enhancing the radiative interaction between quantum electronic transitions is of general
interest. There are two important properties of radiative interaction: the range and the …

We report the theoretical and experimental realization of four types of passive phased array
prisms with various asymmetric acoustic manipulations (AAMs) in air. The designed prisms …

Narrow bandwidth and complex structure are the main shortcomings of the existing
asymmetric acoustic transmission devices. In this letter, a simple broadband asymmetric …

Asymmetric beaming in a piecewise-linear propagation channel is demonstrated for a single
photonic-crystal prism at Gaussian-beam illumination. The used hybrid refraction–diffraction …

Tunable deflection of obliquely incident, linearly polarized terahertz waves is theoretically
studied in a wide frequency range around 20 THz, by combining a thin slab of graphene …

It is shown that strong diffractions and related dual-beam splitting can be obtained at
transmission through the nonsymmetric structures that represent two slabs of photonic …

Transmission through subwavelength apertures enables separation of the incidence half-
space and the exit half-space, which leads to that the spatial distribution of the field in the …

We investigate the propagation of surface plasmon polaritons (SPPs) at the boundary of
metamaterial and topological insulators. Instances of Bi 2 Se 3, Bi 2 Te 3 and metamaterial …
