摘要：The representation of electromagneticstructures by lumped element circuits is revisited. Net-work models can be established by a subsequent ap-plication of system identification and circuit synthesismethods to data obtained by numerical simulation orfrom measurement. Network models provide a com-pact description of electromagnetic structures and cancontribute significantly to the formulation of electro-magnetic field problems and their e.cient solution. Onthe field level network methods are introduced by seg-mentation of the electromagnetic structures and appli-cation of the field form of Tellegen's theorem. Methodsfor synthesis of lumped element models for lossless aswell as lossy linear reciprocal multiports and for ra-diating structures are discussed. The state equationmethod as a general framework for lumped elementnetwork description is presented. Discrete time repre-sentations on the basis of Richards transformation andwave digital filter formulation are introduced
