- If the fields of one transmission line intersect the region around another transmission line, then some of the energy propagating on the first line appears on the second. This coupling discriminates in terms of forward- and backward-traveling waves.

Jan 20, 2021 · The shaft coupling is a mechanical component that connects two rotating shafts such as the driving shaft and driven shaft for purpose of transmitting power. It is used in motors, pumps, generators, and compressors. How does a Shaft Coupling Work? You can connect two shafts together by coupling as shown in the above diagram.
Mar 11, 2021 · We will start by taking a look at what a coupling actually is, how they work, why we use couplings, the different types, and some frequently asked questions. What is a coupling? A coupling connects two shafts , enabling power transmission while allowing for some misalignment or movement.
Apr 17, 2018 · The key idea of a coupler is that a fraction of the signal coming in on Port 1 (P1) will be "coupled to" the output at P3. Meaning the signal will be output from P3. What makes it a directional coupler is that (ideally) none of the signal entering P2 will appear at P3.
In electronics, electric power and telecommunication, coupling is the transfer of electrical energy from one circuit to another, or between parts of a circuit. Coupling can be deliberate as part of the function of the circuit, or it may be undesirable, for instance due to coupling to stray fields.
- Rigid coupling: Rigid couplings are employed when two shafts are perfectly aligned. They are only suitable in close alignment. Their examples include sleeve or muff coupling, split-muff coupling, and flange coupling.
- Sleeve or muff coupling: In the construction of these types of couplings, shaft, key, sleeve or muff are the major components. Also, a hollow cylinder whose inner diameter is equal to the shaft is used.
- Clamp or split-muff or compression coupling: These types of couplings are also known as split muff coupling. The muff or sleeve is made in two helves and is bolted together and they are made of cast iron.
- Flange coupling: Flange coupling comprises two cast iron flanges fitted at the end of each shaft. These flanges are bolted together with bolts to complete the drive.
Mar 22, 2021 · Sharing of a return path results in coupling, often called common impedance coupling, as there is a circuit element common to two or more transmission lines. The simplest situation is a shared impedance rather than a shared transmission line return, so that the return current attributed to one interconnect induces a voltage across the common ...
May 22, 2022 · Coupling can be exploited to realize a new type of element called a directional coupler. The schematic of a directional coupler is shown in Figure 5.8.1 (a) and a microstrip realization is shown in Figure 5.8.1 (b).
