The 6th Australian Microwave Symposium (AMS), sponsored by the IEEE Microwave Theory and Technology Society (MTT-S) Australian Chapters, will take place on February 10-11, 2025, in Gold Coast, QLD, Australia. This biennial conference provides a platform for the national and international microwave, millimetre-wave, and terahertz community to meet and showcase their latest analytical, numerical, and experimental achievements in microwave and RF components, circuits, systems, antennas, and propagation. AMS invites prospective authors to submit original papers in the form of either a one-page abstract or a two-page full paper on all areas of microwave and RF technology. Accepted full papers (2 pages) will be submitted for inclusion in IEEE Xplore. Papers submitted will be peer-reviewed and evaluated based on novelty, significance of the work, and technical content.
