This allows for card-to-reader communication at coupling factors
as much as one order of magnitude lower than is possible with the passive load modulation (PLM) used by contactless cards.
All coupling factors
and power balances for each subsystem are calculated by SEAM.
Similar kind of coupling factors
was also reported by Drioli et al.
The use of an AS3922 AFE provides for tag-to-reader communication at coupling factors
one order of magnitude lower than is possible using conventional methods.
Because the method neglects edge effects from the true, finite size of an array, the results are approximations of far-field patterns and element-to-element coupling factors
A significant reorientation of domains is achieved during polarization of single crystal materials, resulting in higher electromechanical coupling factors
(applied electrical energy is converted into mechanical or acoustic energy) of 90% or more, as compared to 70% for polarized conventional piezoceramics.
