The Swiss Roll Metamaterial Revisited
Zachary Fritts, Anthony Grbic
In this work, we analytically model the Swiss roll metamaterial medium, showing that each unit cell can be thought of as a flux-coupled waveguide terminated in coupled inductors. T…
Analysis of Multi-Tone, Multi-Conductor, Spatially Discrete Traveling-Wave Modulated Loop Networks
Amirhossein Babaee, Zachary Fritts, Steve M. Young +1
This work presents a semi-analytical framework for analyzing spatially discrete traveling-wave modulated (SDTWM) loop networks, which exhibit cavity-like behavior and support discr…
Leaky-Wave Antenna Analysis using Multi-Modal Network Theory with Open Periodic Boundaries
Oscar Senlis, John N. Le, Anthony Grbic +3
This paper introduces two methods for analyzing periodic leaky-wave antennas (LWAs) within a new framework denoted as multi-modal network theory (MNT) with open periodic boundaries…
Physics-Informed Deep Neural Network Design of Reactively Loaded Metasurfaces
Malik Almunif, John Le, Anthony Grbic
A tandem deep neural network approach is presented for the inverse design of reactively loaded metasurfaces with prescribed far-field radiation characteristics. The proposed approa…
Perfectly Matched Metamaterials
Jorge Ruiz-Garcia, Anthony Grbic
Fully harnessing the vast design space enabled by metamaterials to control electromagnetic (EM) fields remains an open problem for researchers. Inverse-design techniques have shown…
Inverse Design of Perfectly-Matched Metamaterials Via Circuit-Based Surrogate Models and the Adjoint Method
Shrey Thakkar, Jorge Ruiz-GarcÃa, Luke Szymanski +2
In this work, perfectly-matched metamaterials (PMMs) are described and combined with inverse design to realize broadband devices. PMMs are discretized metamaterials with anisotropi…
