The TZs are expressed by the adjacent and cross-coupling coefficients. It is revealed that the four stubs affect the filter’s bandwidth and TZ frequencies.

The impact of applied voltage and therefore electric field intensity on the number of permeabilized cells is defined, leading to the establishment of an EP threshold, which is EP conditions and cell dependent.

The FET is based on a graphene monolayer/zirconium-doped hafnium oxide (HZO) heterostructure, being the graphene perforated with a matrix of nanoholes. This choice has two aims: 1) to create a bandgap in the graphene monolayer and 2) to reduce graphene’s thermal conductivity, thereby promoting the generation of a pyroelectric current. Starting from quantum simulations to assess the electrical behavior of the channel, we measured in a cryogenic setup a maximum detected pyroelectric voltage of about 18 mV at 2 GHz and at 100 K.

The design involves creating blind holes and a slot in the dielectric resonator to control the operating frequencies of the three transmission modes (TM010, TM020, and quasi-TM), each forming a passband. By modifying the slot height to convert the third resonant mode into a spurious mode, a dual-band dual-mode filter can be obtained. Besides, two TZs are introduced between adjacent passbands, significantly improving out-of-band rejection. To demonstrate the concept, a triple-band filter utilizing the DW resonator is manufactured, post-processed, and measured.
