TL;DR: In this article, a low-pass rectangular waveguide filter with a wide spurious-free frequency behavior is proposed for the suppression of the fundamental mode over a wide band in much higher power applications than the classical corrugated filter with the same frequency specifications.

TL;DR: The ability to use this technique to detect the presence of tumours in realistic breast phantoms composed of varying quantities of glandular tissue is reported on.

TL;DR: In this article, a method to design high-power low-pass harmonic filters in rectangular waveguide technology is proposed, which consist of a collection of smooth E-plane bandstop elements along the propagation direction and a smooth variation of the filter width.

TL;DR: In this paper, an exact analytical series solution for the synthesis problem derived by the authors from the coupledmode theory is proposed and demonstrated for the design of arbitrary-order differentiators, intended for ultra wideband (UWB) applications in microwave coupledline technology.

TL;DR: In this article, a new design method for dispersive delay lines in coupled-line technology is presented, based on the reflective chirped delay line concept, a continuous modulation of the even and odd-mode characteristic impedances in symmetrical coupled-lines is shown to produce a new structure that presents a flat magnitude response and a linear group delay variation along the operation frequency band.
