Title: Metamaterial Resonators Implemented by RF MEMS for Reconfigurable K-Band Filters
Date: 29th September 2022
Time: 02:30 PM Indian Standard Time (11:00 AM Italian Time)
Abtract: Metamaterials (MM) and radio frequency microsystems (RF MEMS) have been extensively studied for novel high-frequency applications over the past two decades. MMs have been introduced to provide unusual transmission properties determined by the negative value, at the same time, of both the dielectric constant and the magnetic permeability. RF MEMS switches are characterized by a well-established advantage of being entirely passive vs. the limitations of insertion loss and signal distortion introduced by pin diodes. The combination of these two technologies will be presented for potential K-band applications, studying two basic structures in coplanar waveguide (CPW) configurations: (i) U-shaped resonators and (ii) Sierpinski triangles. The design principles, their MM nature, and their utilization in arrays will be discussed for both geometries.
