Spatio-TemporalMetasurface for Real-time 2-D Spectrum Analysis
Shulabh Gupta, Christophe Caloz
A spatio-temporal metasurface is proposed to decompose in real time the temporal frequencies of electromagnetic waves into spatial frequencies onto a two-dimensional plane. The met…
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…
The 2D Linearly Polarized Near-Field Focusing Based on Angularly Discretized Slot Arrays
Menglin Chen, Shulabh Gupta, Zilong Ma +1
A 2-D near-field focusing design is proposed based on the circular slot array waveguide structures, synthesized using the array-factor theory, and demonstrated by full-wave simulat…
Hybrid-cascade Coupled-Line Phasers for High-resolution Radio-Analog Signal Processing
T. Paradis, S. Gupta, Q. Zhang +2
A hybrid-cascade (HC) coupled-line phaser configuration is presented to synthesize enhanced group delay responses for high-resolution Radio-Analog Signal Processing (R-ASP). Using…
Magneto-Electric Dipole Antenna Arrays
Shulabh Gupta, Li Jun Jiang, Christophe Caloz
A planar magneto-electric (ME) dipole antenna array is proposed and demonstrated by both full-wave analysis and experiments. The proposed structure leverages the infinite wavelengt…
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…
Unveiling Magnetic Dipole Radiation in Phase-Reversal Leaky-Wave Antennas
Shulabh Gupta, Li Jun Jiang, Christophe Caloz
The radiation principle of travelling-wave type phase-reversal antennas is explained in details, unveiling the presence of magnetic-dipole radiation in addition to well-known elect…
