Flexible-Resolution, Arbitrary-Input and Tunable Rotman Lens Spectrum Decomposer (RL-SD)
Xiaoyi Wang, Alireza Akbarzadeh, Lianfeng Zou +1
We present an enhanced design -- in terms of resolution flexibility, input port position arbitrariness and frequency-range tunability -- of the planar Rotman lens spectrum decompos…
Loss-Gain Equalized Reconfigurable Phaser for Dynamic Radio Analog Signal Processing (R-ASP)
Lianfeng Zou, Shulabh Gupta, Christophe Caloz
We present a loss-gain equalized reconfigurable phaser for dynamic radio analog signal processing (R-ASP). Such a phaser provides real-time tunable group delay response with all-pa…
Enhancement of Time Reversal Sub-wavelength Wireless Transmission Using Pulse Shaping Technique (submit/1139227)
Shuai Ding, Shulabh Gupta, Rui Zang +3
A novel time-reversal subwavelength transmission technique, based on pulse shaping circuits (PSCs), is proposed. This technique removes the need for complex or electrically large e…
Enhancement of Time-Reversal Subwavelength Wireless Transmission Using Pulse Shaping
Shuai Ding, Rui Zang, Lianfeng Zou +2
A novel time-reversal subwavelength transmission technique, based on pulse shaping circuits (PSCs), is proposed. Compared to previously reported approaches, this technique removes…
A High-Resolution Transmission-Type (TT) Phaser Based on Reflection-Type (RT) Units for Radio Analog Signal Processing (R-ASP)
Lianfeng Zou, Christophe Caloz
A high Radio Analog Signal Processing (R-ASP) resolution transmission-type (TT) phaser based on reflection-type (RT) phaser units is introduced, theoretically studied and experimen…
Planar Reflective Phaser and Synthesis for Radio Analog Signal Processing (R-ASP)
Lianfeng Zou, Qingfeng Zhang, Christophe Caloz
A planar reflective phaser based on an open-ended edge-coupled-line structure is proposed. This phaser is the first reported phaser that combines the benefits of high resolution, i…
Generalized Coupled-line All-Pass Phasers
Shulabh Gupta, Qingfeng Zhang, Lianfeng Zou +2
Generalized coupled-line all-pass phasers, based on transversally-cascaded (TC), longitudinally-cascaded (LC) and hybrid-cascaded (HC) coupled transmission line sections, are prese…
