摘要：

This letter presents a rigorous proof of the maximum number of finite transmission zeros which can be achieved bg 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 M-ij.
