Broadband 1-bit Reconfigurable Intelligent Surface at Millimeter Waves: Overcoming PIN-Diode Degradation with Slotline Ring Topology.

Palomares-Caballero, Ángel; Pérez-Escribano, Mario; Molero, Carlos; Padilla, Pablo; García-Vigueras, María; Gillard, Raphaël[et al.] (IEEE, 2025)

This paper explains the non-idealities that arise when using PIN diodes at millimeter-wave frequencies and the important limitations that they bring in classical configurations of 1-bit slotline reconfigurable unit cells. ...
Metal-Only 3D Unit Cell for Reflectarrays with Independent Dual-Band Operation.

Biedma-Pérez, Andrés; Pérez-Escribano, Mario; Parellada-Serrano, Ignacio; Palomares-Caballero, Ángel; Padilla, Pablo; García-Vigueras, María; Molero, Carlos[et al.] (IEEE, 2025)

This paper presents a metal-only reflectarray based on a 3D unit cell with dual-band capability. The 3D unit cell is a square waveguide whose vertical walls include resonator elements with independent frequency performance. ...
