Explanation

L

Model fidelity

Lmin

Minimum usable fidelity (corresponding

to coarse model)

Lmax

Maximum fidelity (corresponding

to fine model)

R(x)

Response of the EM simulation

model

Rc(x) = R(x,Lmin)

Response of the coarse

simulation model

Rf(x) = R(x,Lmax)

Response of the fine simulation
