Applying TELLEGEN´s Theorem to Calculate the Pulse Responses on a Microstrip DETECTOR´s Strips

The pulse response on a strip of a microstrip detector is calculated while charge, generated in the detector by radiation, is being collected. Both cases, i.e. when the strip is going to collect the generated charge and when it does not, are evaluated. A new method to calculate these pulses is presented. It is based upon the theorem of Tellegen, by which it is shown that the current induced in a detector strip can be calculated by scaling the currents flowing inside the detector (resulting from the movement of the generated charges) by a reference field and then integrating these weighted currents. This field - determined separately - depends solely on the geometry of the detector. Its generality makes the method applicable to other induction problems as well.
