    摘要: A device for preventing secondary light emitted by a laser sight from being seen is disclosed. The device includes a cavity defined by a sidewall and first and second ends of a light containment structure. In some embodiments, the light containment structure is mountable so as to receive light from a laser sight of a weapon through a first opening located at the first end of the light containment structure. The device can include a first portion located at the second end of the light containment structure, and a second opening defined by the first portion and that can pass light from the cavity toward an object such that the object is illuminated to a user of the weapon by the light from the second opening. In some embodiments, the cavity can be configured such that light does not directly illuminate the sidewall.

    摘要: In an electromagnetic cloaking structure, a refractive index distribution has a high refractive index region which is provided around a shielding space and has a maximum value in a plane surrounding the shielding space and in which a refractive index decreases gradually from the centroid of the shielding space along a radial line passing through the plane so as to be close to an average refractive index and a low refractive index region which has a minimum value at two points having the shielding space and the high refractive index region interposed therebetween on a virtual optical axis passing through the shielding space and in which the refractive index increases gradually from the two points in a direction opposite to the high refractive index region on the virtual optical axes, on which the two points are placed, so as to be close to the average refractive index.
