Corrections to “Two Reciprocal Power Theorems for Passive Linear Time-Invariant Multiports”

In
[1]
, we have written several times that
$\mathbf {Z}_{PAM}$
is positive semidefinite, where we should have written that
$\mathbf {Z}_{PAM}$
has a positive semidefinite hermitian part. We have also written that
$\mathbf {Y}_{SAM}$
is positive semidefinite, where we should have written that
$\mathbf {Y}_{SAM}$
has a positive semidefinite hermitian part. The 3 following corrections result.
