The admittance model represents a parallel
connection of a conductor and either a capacitor or inductor.
 
The linear admittance connects the voltage v
with the current i by i =
Y*v. The resistive component is modeled
temperature dependent, so the real part G_actual =
real(Y) is determined from the actual operating
temperature and the reference input conductance
real(Y_ref). A 
conditional heat port is considered. The reactive component
B_actual = imag(Y) is equal to
imag(Y_ref) if frequencyDependent =
false. Frequency dependency is considered by
frequencyDependent = true, distinguishing two
cases:
imag(Y_ref) > 0: capacitive caseB_actual is proportional to
f/f_refimag(Y_ref) < 0: inductive caseB_actual is proportional to
