Very wideband operation of twin-layer inset dielectric guide

Fast and Efficient Analysis of Inset Dielectric Guide Using Fourier Transform Technique with a Modified Perfectly Matched Boundary

“…It is shown that the convergence of our numerical results is very fast and the relative error is one quarter or less of those obtained by the transverse resonance diffraction method [2] under the same condition. The numerical results for single-and double-layered inset dielectric guides agree well with those of literatures [2,8,10] …”

“…Due to the low-cost and easy fabrication, the inset dielectric guide is expected as a promising devise for millimeter-wave integrated circuits and surface wave antennas with a low cross-polarization [5,6]. During the past decade, the modal properties of the guide are extensively investigated by using the effective dielectric constant method [7], the transverse resonance diffraction method [6,[8][9][10], and mode matching method [11]. The effective dielectric constant method utilizes the transverse resonance condition for an equivalent structure with an effective dielectric constant.…”

Analysis of the Inset Dielectric Guide Iris Discontinuity

“…IDG has demonstrated advantages in terms of confinement of, the electromagnetic field, low radiation loss at bends, and devices such as diodes can be included with little performance degradation [1]. The multiple layer IDG can show very wide monomode bandwidth, exceeding that of double ridge waveguide [2], and can include ferrites to establish non-reciprocal effects [3]. In addition, IDG can be integrated with other planar structures such as microstrip line [4].…”
