Comparison of methods for modeling ALAN's power plane structure

Three methods for modeling the power plane structure are discussed. These are circuit modeling using SPICE, model reduction and macromodeling and transmission matrix approach. All these methods assume a magnetic wall at the edges of the planes, including at the split. Each method is used to compute the frequency response and transient response. For the transient response, a continuous periodic pulse is assumed that excites the cavity at the resonant frequency at which the impedance is a maximum. The methods are compared based on accuracy and CPU time. The advantages and disadvantages of each method are discussed.
