Abstract :
This letter presents a rigorous proof of the maximum number of finite transmission zeros which can be achieved by a network of coupled resonators with a fixed topology matrix. Once the topology matrix is fixed, the number of finite transmission zeros cannot exceed this number regardless of the choice of the frequency-independent coupling coefficients Mij
