physical meaning of eigenvalue
Hi all,
I'm analyzing FSS structure.
The MoM analysis is based on Electric Field Integral Equation (EFIE) and leads to the formulation of a homogeneous matrix problem (Z*I=0).
The solution of this problem is performed by an iterative procedure:
for a given value of the propagation phase constant beta,
the frequency range is scanned to find the frequencies where the field equation has a non trivial solution.
The search of these frequency is based on the detection of the determinant zero crossing.
In the slow region(no radiation), the Z (anti-hermitian) eigenvalues are pure imaginary.
In the fast region(radiation), the Z (general complex) eigenvalues are complex.
While frequency's increasing eigenvalues are decreasing (so they couldn't be propagation constants-like).
What is the physical meaning of Z eigenvalues?
Thanks in advance!
Regards.
