The development of advanced materials for electromagnetic wave applications, including microstrip patch antennas and electromagnetic wave absorbers, has become pivotal in addressing the growing demand for efficient and compact devices. Carbon nanotube (CNT)-ferrite nanohybrids have emerged as promising candidates, offering unique synergies between the high conductivity of CNTs and the excellent magnetic properties of ferrites. This talk delves into the synthesis, characterization, and application of CNT-ferrite nanohybrid materials, with a focus on their performance in electromagnetic wave technologies.
Drawing insights from recent advancements, such as the use of Yttrium Iron Garnet (YIG) and Nickel-Zinc Ferrite (NZF) thick films as substrates for microstrip patch antennas, we explore how these hybrid materials enhance bandwidth, resonance frequency, and absorption capabilities. Innovative techniques, including chemical vapor deposition and utilization of eco-friendly precursors like waste cooking oil and linseed oil, have facilitated the scalable production of these materials while maintaining optimal rheological properties for thick film pastes. Furthermore, hybridization strategies, such as integrating coiled CNTs with ferrites, have demonstrated significant improvements in radar absorption and natural resonance frequencies.
By bridging material science and microwave engineering, CNT-ferrite nanohybrids are positioned to revolutionize electromagnetic wave applications, offering lightweight, flexible, and highly efficient solutions. This presentation aims to provide a comprehensive overview of current research trends, highlighting key challenges and future directions in the development of CNT-ferrite nanohybrids for next-generation electromagnetic technologies.
