Abstract A reconfigurable inductorless negative‐refractive‐index transmission‐line (NRI‐TL) metamaterial phase shifter for sub‐6 GHz 5G antenna applications is proposed. The design consists of a microstrip transmission line loaded both in s

High-speed detection and identification of mobile terminals located in the vicinity of highly directive base stations is essential for future mm-wave communication systems. We propose a novel optoelectronic frequency modulated continuous wave (FMCW)

We demonstrate experimentally an optoelectronic oscillator (OEO) in which high side-mode suppression is achieved by cascading a phase modulator-based single passband tunable microwave photonic (MWP) filter with an optoelectronic feedback loop-based i

High-Q microwave photonic filters may be realised with infinite impulse response (IIR) transfer functions, which are implemented typically with all-optical recirculating delay lines (RDL) operating in the incoherent regime. A key problem with these s

This work aims at the establishment of a rigorous full-wave eigenmode analysis technique based on a finite element scheme for the study of terahertz (THz) or photonic/optical unbounded structures. This numerical tool follows the last decades' trend t

The design, fabrication and characterization of a passive linearized field discriminator (FD) filter is presented. The FD filter is designed for silicon-on-insulator (SOI) platform using foundry process design kits (PDKs). Unlike previous FD filters,
