Dispersion in unilateral fin lines with two dielectric layers

Low frequency nonlinear fabry‐perot resonator

“…Figure 7 shows the value of the effective dielectric constant (E," = p 2 / k 2 ) for the dominant mode as a function of the fin width. These results are indistinguishable from those given in [5] and [6]. CONCLUSION In this paper, an approach combining the equivalent magnetic current for slot electric fields with the spectral domain immittance method has been introduced.…”

“…Thus far, electromagnetic models with sufficiently good accuracies have been reported for the waveguide [2] and stripline [6] versions of the symmetrical five-port coupler. The microstrip version, however, continues to elude rigorous treatment.…”

“…where a is discrete valued, a = n77/26, instead of the twodimensional integrals already used. In addition, there are no source terms to make up the right-hand side of Equation (6) so that we have a I I a where Galerkin's method has been used as in (6). Equation (7) is a homogeneous matrix equation that is a function of the propagation constant p which in turn is a function of frequency.…”

“…An application of degenerate parametric amplifier is considered next. A pump wave with amplitude 4 V and frequency f2 = 36.9 kHz is fed at the output end of the line and a signal 6 The input and third harmonic generation wave of frequency fi = f2/2 is fed at the input end. The observed spectrum in the absence of input signal, as shown in Figure 5(a), is found to have single frequency characteristics.…”

A spectral domain approach to electromagnetic coupling through apertures in planar conducting surfaces

“…However, it will also be used to briefly discuss how the preceding formulation can be altered to study apertures in guiding structures such as the fin-line (see Figure 6). Furthermore, by solving the fin-line problem, the accuracy of the approach can be proven by duplicating previously published results by [5] and [6]. The formulation of the fin-line problem proceeds much as the general aperture problem.…”
