Sub-THz Multifunctional Metasurface Dataset for Transmission and Reflection Phase Manipulation

The data correspond to the analysis, synthesis, fabrication, and characterization of a dual-band sub-THz metasurface enabling independent transmission and reflection phase manipulation.

The metasurface operates in the sub-THz regime and supports both transmitarray (TA) and reflectarray (RA) functionalities. The dataset includes data related to:

Unit-cell (meta-atom) design and response

Transmission and reflection coefficients (magnitude and phase)

Dual-band antenna performance

Radiation patterns and gain characteristics

Experimental validation results (anechoic chamber measurements)

The dataset supports key results reported in the associated publication, including:

Full 360° phase control in transmission and reflection

Dual-band operation (D-band and H-band)

High-gain antenna performance

This dataset is intended for reproducibility, benchmarking, and further research in sub-THz metasurfaces, RIS, transmitarrays, and reflectarrays.

A MATLAB script (Processing_TA.m) is included for data visualisation; minor adjustments (e.g., replacing smooth with smoothdata in newer MATLAB versions) may be required.
