In this paper we describe an algorithm for eecient SPICE-level simulation of transmission lines with arbitrary scattering parameter descriptions. That is, the line can be represented in the form of a frequency-domain model or a table of measured frequency-domain data. Our approach initially uses a forced stable decade-by-decadè 2 minimization approach to(More)
In this paper we describe an algorithm for eecient circuit-level simulation of transmission lines which can be speciied by tables of frequency-dependent scattering parameters. The approach uses a forced stable section-by-section`2 minimization approach to construct a high order rational function approximation to the frequency domain data, and then applies(More)

PURPOSE Sooner or later every medical physicist is involved with commissioning and beam modeling of a new linear accelerator (linac) and a new treatment planning system (TPS). In spite of all instructions and training offered by the vendors, at the time a new linac is being purchased and added to the present ones the outside help is not so complete. The(More)
