Latest Patents

One of his latest patents is the "Tunable Metasurface Device." This invention features a metasurface device composed of two sub-cells, each designed to exhibit distinct resonant electromagnetic field (EMF) responses. The device includes a patterned layer and a variable impedance element that can adjust the impedance based on a control signal, allowing for a dynamic EMF response. The integration of these sub-cells enables a cascaded configuration that enhances the overall EMF response of the metasurface unit cell.

Another notable patent is the "Reconfigurable Reflectarray for Passive Communications." This system comprises a reconfigurable reflectarray antenna (RAA) that utilizes a metasurface with dynamically tunable electromagnetic characteristics. The RAA is capable of receiving signals generated independently from the system. A controller communicates with the RAA to generate control signals that dynamically adjust the reflection phase of the metasurface, allowing for effective beam steering of the reflected signals.
