MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641050482 A) filed by Dr. Balaji Biradar; and Dr. Vinodkumar Rathod, Kalaburagi, Karnataka, on April 21, for 'magnetically tunable smart material for controlled electromagnetic shielding.'
Inventor(s) include Dr. Balaji Biradar; and Dr. Vinodkumar Rathod.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "It discloses a magnetically tunable smart material designed for controlled electromagnetic (EM) shielding across a wide frequency range. The invention comprises a composite structure integrating magneto-responsive particles, conductive fillers, and a flexible polymer matrix, wherein the electromagnetic shielding effectiveness can be dynamically adjusted by applying an external magnetic field. The material exhibits reconfigurable electrical conductivity and magnetic permeability due to the field-induced alignment and distribution of embedded particles, enabling real-time modulation of absorption, reflection, and transmission of EM waves. The proposed system allows selective shielding performance tailored to specific frequencies, making it highly suitable for adaptive applications in wireless communication systems, defense electronics, medical devices, and IoT environments. Additionally, the material demonstrates lightweight characteristics, mechanical flexibility, and low fabrication cost, overcoming limitations of conventional static shielding materials. The invention further incorporates a control mechanism to precisely regulate the magnetic field intensity, thereby achieving tunable shielding states ranging from partial transparency to high attenuation. Experimental evaluations indicate improved shielding effectiveness, rapid response time, and repeatable performance under varying environmental conditions. This innovation provides a scalable and energy-efficient solution for next-generation smart electromagnetic interference (EMI) management systems, contributing to enhanced device reliability and reduced signal interference in complex electronic ecosystems."
