Inverse Design of Multi-band Reflective Polarizing Metasurfaces Using Generative Machine Learning
Parinaz Naseri, George Goussetis, Nelson J. G. Fonseca +1
Electromagnetic linear-to-circular polarization converters with wide- and multi-band capabilities can simplify antenna systems where circular polarization is required. Multi-band s…
A Combined Machine-Learning / Optimization-Based Approach for Inverse Design of Nonuniform Bianisotropic Metasurfaces
Parinaz Naseri, Stewart Pearson, Zhengzheng Wang +1
Electromagnetic metasurface design based on far-field constraints without the complete knowledge of the fields on both sides of the metasurface is typically a time consuming and it…
Approach to the Analysis and Synthesis of Cylindrical Metasurfaces with Non-circular Cross Sections Based on Conformal Transformations
Gengyu Xu, George V. Eleftheriades, Sean V. Hum
We present methods for analyzing and designing cylindrical electromagnetic metasurfaces with non-circular cross sections based on conformal transformations. It can be difficult to…
Reconfigurable Reflectarrays and Array Lenses for Dynamic Antenna Beam Control: A Review
Sean Victor Hum, Julien Perruisseau-Carrier
Advances in reflectarrays and array lenses with electronic beam-forming capabilities are enabling a host of new possibilities for these high-performance, low-cost antenna architect…
