Propagation of current waves along randomly located multiconductor transmission lines inside a rectangular resonator is investigated. Two different line configurations are considered: parallel wires and perpendicular lines. The analytical solutions for both types of lines are obtained, using the method of symmetrical lines inside the resonator. Computer realization of this method allows it to obtain a fast solution. Therefore, it becomes possible to investigate statistical properties of induced currents. It could be shown that the mutual coupling of the currents in the wires is strong when the frequency is near resonances in the system "cavity and wires" and relatively small far from these resonances. Stochastization leads to a broadening of the resonance curves.

Open TEM-waveguides are often realized by multiwire structures instead of conducting planes. Especially for largescale nuclear electromagnetic pulse (NEMP) simulators the wire structure is common. In this paper, a generic open TEM-waveguide structure is analyzed using the transmission-line super theory (TLST). The concept of the numerical implementation is thoroughly described independent of a particular programming language. The TLST comprises full Maxwell's equations assuring that higher order modes and radiation effects are included. Currents along the lines and the total radiated power outside the simulator are calculated. Inside the simulator the magnetic field is estimated in the working volume, and the result is verified by experiment. The presented theory is applicable not only to the described simulator structure but also to a variety of wire-based problems in electromagnetic compatibility.

The current induced by an incident electric field can convert from the antenna mode to differential mode at unbalanced terminals of transmission lines (TLs), causing severe interference to a number of applications such as broadband power line communication, especially in the very high frequency (VHF) band. The previous work on modeling the current conversion is not applicable to VHF. We present a new model of the VHF current conversion which includes a general formula for the antenna mode characteristic impedance and two solutions to the formulated problem: 1) a numerical solution referred to as the antenna theory numerical (ATN) approach, which gives the exact value of the characteristic impedance; 2) an analytical solution referred to as the enhanced TL approximation (ETLA) approach, which gives the mean of the characteristic impedance. This is the first reported work to obtain the antenna mode characteristic impedance by the antenna theory. Furthermore, the ETLA approach outperforms the previous frequency-independent solution and requires a reduced complexity over the ATN approach. Our model is general as it converges to the previous model at lower frequencies. Simulation results also show the relationship between the antenna mode characteristic impedance and the power of the interference caused by the current conversion.Index Terms-Antenna theory, electric field effects, electromagnetic interference (EMI), transmission line modeling, transmission line theory, VHF radio communication.
