MUMBAI, India, Feb. 27 -- Intellectual Property India has published a patent application (202641017863 A) filed by Vel Tech Rangarajan Dr. Sagunthala R&D Institute Of Science And Technology, Chennai, Tamil Nadu, on Feb. 17, for 'dual-domain miniaturized metamaterial absorber for microwave applications and terahertz biosensing.'
Inventor(s) include Dr. B. Ashwanth.
The application for the patent was published on Feb. 27, under issue no. 09/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses a multi-resonant metamaterial absorber configured for dual-domain electromagnetic operation. The absorber comprises a dielectric substrate, a continuous metallic ground plane, and a patterned metallic resonant layer including a central circular ring, symmetrically arranged L-shaped conductive arms, terminal stub extensions, and quadrant-based circular zigzag resonators. The geometrical coupling between these elements generates multiple discrete resonance peaks within microwave frequency bands while maintaining angular and polarization stability. The resonant topology is proportionally scalable to micrometer dimensions for operation in the terahertz frequency range. In the scaled configuration, the absorber functions as a refractive index sensing device, wherein variations in dielectric properties of an analyte layer produce measurable resonance frequency shifts. The invention provides a structurally compact, fabrication-compatible absorber capable of electromagnetic shielding and high-sensitivity terahertz biosensing using a unified geometric configuration."
