Nous étudions une quantité KVol liée au volume sur la strate ℋ(2) des surfaces de translation genre 2, avec singularité conique. donnons suite explicite L(n,n) telles que KVol(L(n,n))→2 quand n tend vers l’infini, 2 étant l’infimum conjectural ℋ(2).
This paper presents a novel third-order cross-coupled rectangular cavity filter by using standard low-temperature cofired ceramic (LTCC) technology, in which the multilayer substrate integrated waveguide (SIW) is implemented. Particularly, the desired filter has a single finite frequency attenuation pole at j4.0 with asymmetrical frequency selectivity. An experimental band pass filter (BPF) has...
