In contrast\, over the past three decades\, growing atte ntion has been directed toward orbital angular momentum (OAM)\, which aris es from helical (twisted) phase fronts and provides an additional degree o f freedom through its orthogonal modal structure. In this talk\, we explor e the use of OAM for integrated sensing and communications (ISAC)\, with t he goal of enhancing spectral efficiency and spatial resolution in automot ive scenarios. Unlike conventional uniform circular array (UCA)-based impl ementations\, our approach employs a uniform linear array (ULA) with trave ling-wave antennas to synthesize multiple Laguerre-Gaussian vortex beams. The proposed system embeds communication data within radar waveforms while enabling joint estimation of target position and velocity using radar-onl y frames. An OAM-based mode-division multiplexing strategy is used to sepa rate sensing and communication functionalities\, ensuring reliable paramet er recovery. We conclude with perspectives on the future of ISAC systems.\ n\nSpeaker(s): Dr. Mishra\n\nAgenda: \n4:30-5:30 PM Lecture and Q&A\n\nRoo m: Seminar Room B \, Bldg: San Diego Mission Valley Branch Library\, 1F\, 2123 Fenton Pkwy\, San Diego\, California\, United States\, 92108\, Virtu al: https://events.vtools.ieee.org/m/562094 LOCATION:Room: Seminar Room B \, Bldg: San Diego Mission Valley Branch Lib rary\, 1F\, 2123 Fenton Pkwy\, San Diego\, California\, United States\, 92 108\, Virtual: https://events.vtools.ieee.org/m/562094 ORGANIZER:lei.sun@ieee.org SEQUENCE:15 SUMMARY:2026 VTS Hybrid Distinguished Lecture: Twisted Signals for ISAC via OAM Vortex Beams URL;VALUE=URI:https://events.vtools.ieee.org/m/562094 X-ALT-DESC:Description: <br /><p class="MsoNormal">Electromagnetic waves ar e characterized by their amplitude\, frequency\, and state of polarization -- also referred to as spin angular momentum (SAM)\, associated with circ ular polarization and recognized for over two centuries. In contrast\, ove r the past three decades\, growing attention has been directed toward orbi tal angular momentum (OAM)\, which arises from helical (twisted) phase fro nts and provides an additional degree of freedom through its orthogonal mo dal structure. In this talk\, we explore the use of OAM for integrated sen sing and communications (ISAC)\, with the goal of enhancing spectral effic iency and spatial resolution in automotive scenarios. Unlike conventional uniform circular array (UCA)-based implementations\, our approach employs a uniform linear array (ULA) with traveling-wave antennas to synthesize mu ltiple Laguerre-Gaussian vortex beams. The proposed system embeds communic ation data within radar waveforms while enabling joint estimation of targe t position and velocity using radar-only frames. An OAM-based mode-divisio n multiplexing strategy is used to separate sensing and communication func tionalities\, ensuring reliable parameter recovery. We conclude with persp ectives on the future of ISAC systems.</p><br /><br />Agenda: <br /><p>4:3 0-5:30 PM Lecture and Q&amp\;A</p>\n<p>&nbsp\;</p> END:VEVENT END:VCALENDAR
