摘要：
In the design of a bandpass filter, the mutual inductance M and the mutual capacitance C-m between two resonators are needed. In this paper, the speed of energy exchange between the coupled LC resonators is related to M and C-m and is defined as the coupling coefficient. Subsequently, the effective M and C are determined by deriving the coupling coefficient between the electromagnetic resonators. In this way, a basis is provided on which the filter design theory established previously for the LC resonator circuits is extended to the electromagnetic circuits. (C) 2006 Wiley Periodicals, Inc.
