The dataset consists of training and test data and label matrices for single-pixel compressive DoA estimation for mmWave metasurface. The dataset will be uploaded soon. Currently, a small part of the dataset can be accessed through this repository.

This paper presents an overview of Unidirectional

Loop Metamaterial (ULM) structures and applications. Mimicking

electron spin precession in ferrites using loops with unidirectional

loads (typically transistors), the ULM exhibits all the

fundamental properties of ferrite materials, and represents the

only existing magnetless ferrimagnetic medium. We present here

an extended explanation of ULM physics and unified description


of its component and system applications.
