F**k you! A********e ! U f**********g moron. If i would have known the answer then i would'nt have asked the question.
initially the induced emf i.e.,self inductance is high than mutually induced emf in the other .....so coefficient of coupling is high
3 types: 1.electromagentic waveguides 2.optical waveguides 3.acoustic waveguides
Mutual induction only
Lennart Marin has written: 'On the coupling between two adjacent rectangular waveguides through a slot in the common wall' -- subject(s): Wave guides
It is a measure of how close is a coupling between two coils it gives an idea of wat portion of the flux produced by one coil links with the other coil
Piezoelectric materials typical experience a reduction in the remnant polarization. The effectively reduces the coupling between mechanical and electrical energy reducing the electro-mechanical coupling coefficient.
The measurement of stiffness of the electromagnetic coupling between the rotor and the stator is carried out by the synchronizing power coefficient. If the value of Psyn is large, the coupling is stiff or rigid. For a too rigid coupling, with change of load or supply, the machine will be under shock which may damage the rotor of the winding
waveguides are used instead of coax because at the high microwave frequencies coax would radiate the signal right through its shield. waveguides do not replace antennas.

There are many like flexible coupling, jaw coupling, sleeve coupling, tire coupling, pin and bush coupling, rigid coupling, etc
transformer coupling
