Chiral Mirrors
Conventional mirrors convert right-handed circularly polarized waves (RCP) into left-handed circularly polarized waves (LCP) and vice versa, see Fig. 1(a-c). Here we demonstrate a novel type of chiral mirror that will reflect one circular polarization without changing its handedness, while absorbing waves of the opposite handedness, see Fig. 1(d-f). This functionality, which fundamentally relie...
متن کاملOptimization of chirped mirrors.
We demonstrate that a highly efficient global optimization of chirped mirrors can be performed with the memetic algorithm. The inherently high sensitivity of chirped-mirror characteristics to manufacturing errors can be reduced significantly by means of the stochastic quasi-gradient algorithm. The applicability of these algorithms is not limited to chirped mirrors.
متن کاملMirrors, mirrors on the wall…the ubiquitous multiple reflection error.
Participants decided when somebody, Janine, could see their face in a horizontal row of adjacent mirrors mounted flat on the same wall. They saw real mirrors and a shop-dummy representing Janine. Such coplanar mirrors reflect different, non-overlapping areas of a scene. However, almost everybody made an unexpected error: they claimed that Janine would see her face reflected in multiple mirrors ...
متن کاملRelation between attractive force and keeper surface characteristics of iron-neodymium-boron magnetic attachment systems.
The purpose of this study was to evaluate the influence of heating, cast bonding, and subsequent polishing procedures on attractive force of magnetic attachments. Two magnetic attachment systems with keepers of different chemical compositions (Hicorexslim 3013, 447J1; Magfit EX400, AUM20) were employed. Keepers examined were: (1) untreated; (2) heated; (3) cast-bonded with Ag-Pd alloy; (4) cast...
متن کاملSoft-tissue facial characteristics of attractive Italian women as compared to normal women.
OBJECTIVE To compare the facial characteristics of two different groups of attractive women with those of reference women. MATERIALS AND METHODS The three-dimensional coordinates of 50 facial landmarks were collected in 71 healthy reference women (18-30 years old) and in 24 coetaneous "attractive" women selected during two different beauty competitions; soft tissue facial angles, distances, a...
