Modeling of Electromagnetic Wave Propagation with Tapered Transmission Line

Abstract

Tapered transmission line was used for impedance matching, for high voltage pulse, and atmospheric medium is applied to characteristic equation of tapered transmission line and reflection coefficient so that nonlinear load and circuit modeling of atmospheric medium was simulated by electromagnetic transient program (EMTP). A characteristic of atmospheric medium and Time delay are decided by inductance and capacitance of tapered transmission line. For electromagnetic wave propagation modeling, in this paper, tapered transmission line is implemented. It is difficult to model tapered transmission line directly. Other transmission line that can be expressed by the circuit is used. So object of this paper is efficient modeling of tapered transmission line.

“…Instead, the tapered design introduces a smoother impedance transition between the source and load and beneficially allows for adjustment of the transmission line length, a key component of the overall impedance and signal reflection , as shown in where j is the imaginary unit, β z is the electrical length of the tapered section, and Z L and Z 0 are the effective impedances of the load and line, respectively. By iterating from our resonator load along the tapered adapter to the 50 Ω SMA, a sequential method to track the impedance along the line is enabled without the need to implement more complex taper designs …”

“…By iterating 2 from our resonator load along the tapered adapter to the 50 Ω SMA, a sequential method to track the impedance along the line is enabled without the need to implement more complex taper designs. 38 Data were collected using the experimental setup shown in Figure 2a,b. The experimental setup consisted of the resonator design connected to a vector network analyzer (VNA, Keysight N9552A).…”
