Broad-band impedance matching of dispersive waveguides - the white light cavity approach

We present a new approach for broadband impedance matching, overcoming structural and material dispersion. The transformer constitutes a critically-coupled white light cavity, implemented by a dual-section structure. The result is minimal reflectivity over broad spectral band. The approach is demons...

Description
Summary:We present a new approach for broadband impedance matching, overcoming structural and material dispersion. The transformer constitutes a critically-coupled white light cavity, implemented by a dual-section structure. The result is minimal reflectivity over broad spectral band. The approach is demonstrated in the millimeter waves band.
