This paper reports a detailed study of a graphene-based metasurface to function as tunable
broadband linear to circular polarization converter in the terahertz gap. This device provides …

A tunable terahertz four-port multiple-input-multiple-output (MIMO) graphene-based
microstrip patch antenna with self-multiplexing ability is designed and numerically studied …

This work presents a simple graphene-based tunable ultra-wideband (UWB) metasurface for
terahertz application. The unit cell comprises a silicon dioxide (SiO 2) substrate sandwiched …

We present the design and analysis of a graphene metasurface-based cross polarization
converter operating within the terahertz gap for detecting biomolecules over a broad spectral …

A multicontrollable terahertz perfect absorber has been proposed and demonstrated
numerically through an L-shaped metasurface tri-layer structure. The proposed tri-layer …

This study aims to design a metamaterial sensor to detect glucose levels in the human body
so that the severity of diabetic patients can be determined. The biomolecules are placed …

A crucial point of restricting its development and application is the lack of dynamically
tunable devices in the terahertz fields. In this work, shape memory alloys (SMAs) are …

A multifunctional metasurface using all dielectric structure comprising an array of InAs
square pillar over the InSb substrate has been realized. The considered metasurface shows …

Terahertz metasurfaces with pixelated meta-atoms were designed for linear-polarization
conversion and absorption. The differences between the two functionalities emerged from …
