Floquet-Mode Solutions of Space-Time Modulated Huygens' Metasurfaces
Shulabh Gupta, Tom. J. Smy, Scott A. Stewart
A rigorous Floquet mode analysis is proposed for a zero thickness space-time modulated Huygens' metasurface to model and determine the strengths of the new harmonic components of t…
Finite-Difference Time-Domain (FDTD) Modelling of Space-Time Modulated Metasurfaces
Scott A. Stewart, Tom J. Smy, Shulabh Gupta
A finite-difference time-domain (FDTD) modelling of finite-size zero thickness space-time modulated Huygens' metasurfaces based on Generalized Sheet Transition Conditions (GSTCs),…
Exact Finite-Difference Time-Domain Modelling of Broadband Huygens' Metasurfaces with Lorentz Dispersions
Tom J. Smy, Shulabh Gupta
An explicit time-domain finite-difference technique for modelling zero-thickness Huygens' metasurfaces based on Generalized Sheet Transition Conditions (GSTCs), is proposed and dem…
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…
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…
