In its most general form, the magnetoelectric effect (ME) denotes any coupling between the magnetic and the electric properties of a material. [ 1 ] [ 2 ] The first example of such an effect was described by Wilhelm Röntgen in 1888, who found that a dielectric material moving through an electric field would become magnetized. [ 3 ]
MESO devices operate by the coupling of the magnetoelectric effect with the spin orbit coupling. [3] Specifically, the magnetoelectric effect will induce a change in magnetization within the device due to an induced electric field, which can then be read out by the spin orbit coupling component which converts it into an electric charge.
The coupling coefficient is a convenient way to specify the relationship between a certain orientation of inductors with arbitrary inductance. Most authors define the range as 0 ≤ k < 1 {\displaystyle 0\leq k<1} , but some [ 28 ] define it as − 1 < k < 1 {\displaystyle -1<k<1\,} .
Some aquariums use magnetic drive pumps, which have a magnetic coupling between the motor on the dry side of an aquarium wall and the propeller or impeller in the water on the other side of the wall. [4] This coupling features two face-to-face magnetized disks: the driving magnet on the dry side, and the driven magnet on the underwater side.
In filters with cross couplings, it is convenient to characterize all filter couplings as a whole using a coupling matrix of dimension ,. [ 4 ] [ 12 ] It is symmetrical. Every its off-diagonal element M i j {\displaystyle M_{ij}} is the coupling coefficient of i th and j th resonators k i j . {\displaystyle k_{ij}.}

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 .
