Analysis of Laterally Open Periodic Waveguides by Means of a Generalized Transverse Resonance Approach

Simulation-Assisted Efficient Computation of the Dispersion Diagram of Periodic Structures: A comprehensive overview with applications to filters, leaky-wave antennas and metasurfaces

“…In principle, to our knowledge, not much can be done to circumvent drawback 2 from the section "Drawbacks," when significant although possible alternatives involving the development of the in-house, full-wave eigenmode solver have been proposed in [41] and [42]. However, different solutions involving commercial simulators have been reported to overcome drawback 1 [43]- [46].…”

Efficient Mode-Matching Analysis of 2-D Scattering by Periodic Array of Circular Cylinders

“…A standard mode-matching technique in [3] and [9] is still used to formulate the analytic dispersion and scattering equations for rectangular [10] and circular cylindrical [11] structures. Using staircase approximation and the generalized scattering matrix, open periodic waveguides with an arbitrary unit cell can be approximately analyzed in the Cartesian coordinate system [12]. A complex mode-matching method combined with the perfectly matched layer (PML) [13] opened a new way to obtain the reflection and transmission spectra of optical-waveguide interconnects.…”

Analysis and synthesis of leaky-wave devices in planar technology

“…To solve this drawback a full-wave analysis of the SIW can be performed, and therefore an accurate value for the propagation constant can be obtained in a wider range of values of s/d. To this aim, some techniques based on the finitedifference time domain method or the finite-difference frequency domain [11], the boundary integral-resonant mode expansion (BI-RME) method [12], the method of lines [13] and the transverse resonance method [14], [15] have been proposed.…”
