Antennas in Space: Advances and Challenges

Room: 314, Bldg: Walter Light Hall, 19 Union St, Kingston, Ontario, Canada

YOU'RE INVITED!Join the IEEE Queen's Branch in welcoming Dr. Jawad Siddiqui from the IEEE Antennas and Propagation Society to speak with students about new work in antennas for the space domain, as well as the opportunities available to students through the IEEE. All students are welcome!The talk will explore the evolving role of antenna technologies in modern space applications, with a particular focus on CubeSats and rocket platforms. It will discuss key challenges such as size constraints, thermal management, deployment mechanisms, and radiation effects, as well as emerging trends in adaptive, reconfigurable, and additive-manufactured antennas designed for the space environment. The presentation will also highlight opportunities for students and professionals to engage with the IEEE Antennas and Propagation Society (AP-S), including the benefits of membership and participation in its SIGHT (Special Interest Group on Humanitarian Technology) initiatives that apply antenna and propagation technologies for societal impact. The speaker will welcome questions from the audience. The seminar will end with an interactive discussion with the speaker about opportunities for students in the IEEE. These include best practices for achieving funding awards through the IEEE, with a focus on the <a href="http://AP-S.Co-sponsored" target="_blank" title="AP-S.Co-sponsored">AP-S.Co-sponsored by: Abedal Rahman ShehabiSpeaker(s): Dr. SiddiquiRoom: 314, Bldg: Walter Light Hall, 19 Union St, Kingston, Ontario, Canada

Nanobubbles: Tiny Agents Driving Huge Impacts in Contrast-Enhanced Vascular Ultrasound Imaging

350 Victoria Street, Toronto Metropolitan University, Room: KHE321C, Toronto, Ontario, Canada, M5B 2K3

Abstract: Nanobubbles (NBs) are promising ultrasound contrast agents capable of enhancing both vascular and extravascular imaging. Their spatially uniform scattering under repeated exposure enables consistent and durable enhancement. This study evaluates NB-enhanced ultrasound using compound amplitude modulation (cAM) and plane-wave imaging (PWI) on the Vevo F2 system (Fujifilm VisualSonics Inc.) in both phantoms and in vivo mice. Phospholipid-shelled NBs (~250 nm) were tested in phantoms (~10⁹ NBs/mL) and in mouse kidneys (~10¹¹ NBs/mL). While cAM was sufficient in phantoms, it was inadequate in vivo due to breathing motion and incomplete tissue suppression. To address this limitation, a new PWI-based methodology was developed for NB-enhanced imaging, integrating high-frame-rate acquisition and advanced signal processing to achieve robust vascular visualization without amplitude modulation or pulse inversion. This approach establishes a practical framework for NB-enhanced vascular ultrasound imaging and demonstrates strong potential for preclinical and clinical <a href="http://translation.350" target="_blank" title="translation.350">translation.350 Victoria Street, Toronto Metropolitan University, Room: KHE321C, Toronto, Ontario, Canada, M5B 2K3
