Building Physics Laboratory building case study showcases the refurbishment of the southern façade with the Anidolic Ceiling system‚ achieving higher luminance and illuminance factors. The Anidolic Blinds are a façade system where the non-imaging optics prevent high solar rays but allow lower altitude diffuse light into the room. Solar Tubes or “Tubular Daylighting Devices‚” an alternative means of redirecting daylight into a space‚ where it uses some of the same principles as the Anidolic daylighting

optical communication is a kind of communication that use light propagation to send data between two points. Free Space Optics are capable of up to 2.5 Gbps of data‚ voice and video communications through the air‚ allowing optical connectivity without requiring fiber-optic cable or securing spectrum licenses. So we can use LED’s or Laser for transmission data. Free Space Optics (FSO) technology is relatively simple. It’s built on a laser transmitter and a receiver to provide full duplex capability

range. A lens antenna consists of a lens proper and of a feed. The shape of the lens depends on the refractive index n (the ratio of the phase velocity of propagation of a radio wave in a vacuum to that in the lens). A decelerating lens antenna‚ as in optics‚ is one for which n > 1. An accelerating lens antenna (without an optical analogy) is one for which n < 1. The feed is usually a horn antenna that generates a spherical wave front or an antenna array that produces a cylindrical wave front.
