- Detta är en avhandling från Department of Electrical and Information Technology, Lund University
Sammanfattning : Sum rules and physical limitations within electromagnetic theory and antenna theory have received significant attention in the last few years. However, the derivations are often relying on application specific and sometimes unsupported assumptions, and therefore a mathematically rigorous and generally applicable approach seems timely.

2. Sum rules and constraints on passive systems - a general approach and applications to electromagnetic scatteringDetta är en avhandling från Department of Electrical and Information Technology, Lund University
Sammanfattning : Physical processes are often modeled as input-output systems. Many such systems obey passivity, which means that power is dissipated in the process. This thesis deals with the inevitable constraints imposed on physical systems due to passivity. A general approach to derive sum rules and physical limitations on passive systems is presented. LÄS MER
