“…The use of these resonators, either in propagative [8] or in evanescent mode [9], [10] topologies, provides a reduction of around 50% in mass and volume [8], [9], an increase of thermal stability [11], [12], and, if the dielectric rods are all inductive or H plane, an increase of out-of-band rejection and better field distribution (lower voltage magnification factor), because the peaks of electric field within these filters are concentrated inside the dielectric posts, thus producing a smaller level of electromagnetic field, outside the dielectric posts, than in the case of the all metallic filters [13]. Considering that the multipactor effect can only occur outside the posts, since inside the all inductive dielectric posts breakdown processes would require significantly much more power, it follows that these filters need more power for the multipactor discharge to take place.…”
