Computation of radiated electric fields from cables using the 1D time-domain and frequency-domain TLM methods

An intermediate level modeling method aimed at providing a faster solution with less computing resources to allow designers to obtain rapid approximations is valuable. This paper presents a modeling technique to speed up the evaluation of radiated fields from the interconnect cables. Based on the Hertzian dipole radiation theory and the 1D time domain and frequency domain transmission line modeling (TLM) solutions, the radiating cables are modeled by the sum of a large number of short dipoles. The proposed prediction technique of radiation is verified by a bare wire cable radiation measurement.
