Loop Loop couplers are a special type of coupler normally used in antennas. A coaxial connector serves are one of the terminals. Multihole A waveguide directional coupler with more than one output. It ...

Furthermore, they form important active or passive photonic devices by themselves, such as waveguide couplers and modulators. In this chapter, we consider the basic characteristics of linear, lossless ...

From ETH Zurich: “Schematics of the experimental set-up (left) and wave propagation (right): Waveguide 1 can be heard perfectly by waveguide 3, but not by waveguide 2, and waveguide 3 can be ...

Holographic photopolymers can be cast onto and around other optical elements, then patterned with a 3D routed waveguide to form hybrid integrated photonics. While multi-photon initiation can be used ...

Here is a classic project used to increase wireless signal strength. Cantennas focus using a waveguide very much like a magnifying glass focuses light. [Robert] made a Natural Light beer cantenna ...

Electromagnetic, acoustic, and elastic waveguides are commonly used in communication, imaging, and signal isolation to facilitate efficient directional transmission of signals. However ...

See "directional coupler" in this glossary ... but derives a higher gain through a small waveguide rather than several meters of fiber. The interference in signal transmission or reception ...

A device that connects a terminal or computer to the handset of a telephone. Acoustic couplers were widely used in the days of analog telephone networks in the 1970-1990s time frame to convert the ...
