In this paper, a graph-theory-based approach for representing planar mechanisms is presented, the Santiago Portilla method (SPM). From the corresponding adjacency matrix, SPM generates an extended ...

A planar antenna array exhibiting polarization-switchable endfire and ±broadside radiation without the employment of lumped components is proposed. The antenna is denoted as symmetrically stacked ...

The past 2 years have seen the uniquely rapid emergence of a new class of solar cell based on mixed organic–inorganic halide perovskite. Grain boundaries are present in polycrystalline thin film solar ...

Planar chiral structures respond differently for oppositely handed incident light, and thus can produce extraordinary chiroptical effects such as circular conversion dichroism (CCD) and asymmetric ...
