La conception de dispositifs passifs volumiques imprimés par fabrication additive 3D plastique pour des objectifs pédagogiques est présentée. Deux aspects sont exposés dans ce papier, le premier étant les dispositifs à réaliser dans le cadre de projet de master qui s'étalent sur plusieurs semaines avec une réalisation finale par impression plastique 3D. Le second étant l'utilisation de dispositifs déjà imprimés pour la compréhension physique du dispositif et de son réglage avec un appui logiciel lors de séance de travaux pratiques. L'impression 3D plastique permet, par le caractère faible coût des fabrications et de mise en oeuvre aisée, des temps de fabrication de quelques heures. Des prototypes pour des projets de master microondes peuvent être ainsi envisagés. L'investissement des étudiants se faisant sur l'ensemble des phases d'ingénierie dans la philosophie "Do It Yourself". Les travaux pratiques deviennent plus ludiques grâce à des structures à assemblage et réglage rapides.

To reduce costly prototyping and allow for short design cycles in the design of tuningfree waveguide filters, it is important to be able to perform yield analysis in short time frames. For many filter topologies, this is infeasible by direct application of full wave EM solvers. In this paper, a simple and fast method for yield-driven design of direct-coupled waveguide filters with minimum use of full wave EM solvers is presented. The method is based on training a circuit model by including the sensitivities of each coupling to changes in dimensions and frequency. It is shown that this model gives accurate results for dimensional changes within typical production tolerances for waveguide components, and it is thus possible to perform fast tolerance analysis with high accuracy for yield-driven design. Examples of tolerance analysis for some filter topologies are shown. Also included is a comparison with measurements.

“…The design and optimization of iris coupled, waveguide cavities using CAD tools is common in achieving bandpass tilter characteristics [117][118][119]32]. Filters of this type have resonating cavities (where each guide cavity is roughly )J2 in lengili), coupled by thin (or thick) irises with coupling apertures between any two cavities.…”

“…Filters of this type have resonating cavities (where each guide cavity is roughly )J2 in lengili), coupled by thin (or thick) irises with coupling apertures between any two cavities. While sorne designs make use of varying the thickness of each iris as design parameters [117,119], the 2-cavity filter described below has irises of constant, small, thickness (see Figure 6.8).…”
