Hi,
Is there an equivalent transformer circuit to model piezoelectric materials? Something like modeling the mechanical side of piezo into an equivalent electrical circuit on the primary side and the electrical equivalent of piezo on the secondary side. In this case, how to determine the...
Thanks for the reply. Using EM solvers is the only way to find coupling/mutual inductance between coils of different geometries? Also, I find that EM solvers are used for designing inductors in PCB which have very small geometries. Is it accurate enough to simulate coils of the sizes I...
Hi there,
Are there any formulas that give the coupling coefficient between 2 coils based on the distance of separation and other such parameters? I need to calculate the coupling coefficient for the single turn coil ( of say diameter 20cm) and flat spiral coil ( say Inner dia = 10cm, Outer...
I meant a packaging cardboard. I am using it as a base to make flat spiral coils and want to test them. But I cannot find the loss tangent data for the frequency I want to test. The cardboard material has negligible loss tangent at 915 MHz. But does this imply anything at all at frequencies <25 MHz?
Hi,
I would like to know the loss tangent of cardboard at <25MHz. I tried searching for values, but without any luck. Any help would be appreciated. Thanks.

Wireless Power Transfer via Strongly Coupled Magnetic Resonances, Science, 2007 - This is the first paper on wireless power carried out in MIT.
I was going through some IEEE papers on wireless power transfer and found that most of them employ a 4 coil system. 2 of them are resonant coils which are typically multi-turn coils and there are 2 single turn coils in each transmitter and receiver. So essentially the transmitter has a single...
