metamaterials and metasurfaces

Ultrasonic flowmeters that use transit-time ultrasonic transducers face measurement errors due to ``crosstalk,'' whereby the working signal travels through the pipe wall and couplings, interfering with the signal from the fluid.  Although various procedures have been proposed to solve the issue of crosstalk, they're limited to low-frequency ranges, or they are not effective in high-pressure environments.

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.
