Recently, Prof. Changqing Chen's group at Tsinghua University has developed a theory to characterize the localized static ...

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 ...

such as waveguide couplers and modulators. In this chapter, we consider the basic characteristics of linear, lossless dielectric waveguides. Optical fibers are discussed in Chapter 3. Other waveguide ...

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 ...

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 ...

KRYTAR’s technological advances provide excellent operating performance of this new 2-way power divider. Model 6005100 covers the full frequency range from 0.5 GHz to 10.0 GHz with greater than 19 dB ...

A simple workaround for all this was an acoustic coupler, a device that played your modem’s sounds directly into a phone’s receiver without any electrical connection. Modem speeds were slow ...

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 ...

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 ...
