Research Projects / Patents

Spoof Surface Plasmon Polariton Waveguide for Sensor based Applications

This patent discusses the Spoof SPP waveguide design with different dielectric materials and examining its transmission and refelection coefficients for different dielectric properties. In this patent we examined the dielectric materials like teflon, rogers, FR4 and oxide layers and explored the dielectric properties of the SSPP.

A HYBRID SENSOR DEVICE FOR DETECTING DIELECTRIC CONSTANTS OF MATERIALS

The innovation of this work lies in the design and placement of the SSPP feeding structure and its unit cell in conjunction with the Yagi Uda and SRRs. Since SSPP operate at low frequency ranges, this design enhances the transmission coefficient | S 21 | within 5.5 GHz compared to that of existing literature that does not incorporate SSPP techniques. The proposed SSPP sensing platform offers precise measurement of both solid and liquid samples with improved sensitivity. Observations indicates a correlation between the

SYSTEM AND METHOD FOR EXCITATION OF DIELECTRIC ROD ANTENNA USING SPOOF SURFACE PLASMON POLARITON

This patent introduces a novel method for utilizing spoof surface plasmon polaritons (SSPP) to feed a dielectric rod antenna. The design features a simple dielectric rod antenna made from FR-4 material with a relative permittivity of 4.3. This design promises to offer an improved gain of up to 16.85 dBi with an antenna length of 7.6 ? 0 , surpassing traditional tapered dielectric rod antennas and their feeding configurations. By optimizing the design, we achieved impedance matching at 7.1 GHz.

A PLANAR SINGLE SUBSTRATE HEXAGONAL COMPLEMENTARY SPLIT RING RESONATOR (CSRR) SYSTEM AND METHOD THEREOF

The proposed invention reduces the loading effects associated with external coupling/probing circuitry by strategically placing them within the near field zone of two printed yagi uda antennas, which are excited by spoof surface plasmon polaritons(SSPPs). This placement effectively minimizes the additional loading impacts on the resonant characteristics of the microwave hexagonal split- ring resonators(HSRRs)

AI-ENABLED SENSOR SYSTEM FOR MEASURING THE QUALITY OF BIOLOGICAL SAMPLES AND IMPURITIES IN MATERIALS

This invention relates to an advanced AI-enabled sensor system designed to analyze the quality of biological samples and detect impurities in various materials with high precision and reliability. The system integrates smart sensing modules with artificial intelligence algorithms to provide real-time, non-destructive, and accurate evaluation of biological and material properties. The sensor unit employs multi-modal detection methods such as optical, dielectric, and spectroscopic sensing.
