In order to realize these future CPSs, the mmIDs used to form these systems need to be highly manufacturable, operate energy autonomously, have compact form factor, provide long-reading ranges with orientation-agnostic operation, and be able to be localized accurately to create a detailed CPS of an environment.Three specific topologies of backscatter tags operating in this 5G\/mmWave bands are presented. The first technology presented is a chipless cross-polarized reflectarray wireless strain sensor presenting the first every off-axis structural health monitoring fully-passive sensor for local strain monitoring for both adhered or embedded form-factors. Along with the design and characterization of the wireless strain sensor, a multi-tag interrogation framework is presented for future ubiquitous structure health monitoring CPSs. The next technology is the first-ever retro-directive harmonic mmID comprised of dual Rotman lenses and a fully-passive frequency doubler circuit. The mmID is interrogated with a proof-of-concept harmonic frequency modulated continuous wave radar providing accurate long range ranging of the energy autonomous tag as well as sub-mm accuracy at medium range of the radar. The mmID is envisioned to provide ultra-long range operation future localized sensing and tracking applications up to multiple kilometers. The last technology builds on the previous two by combining a 3D lens with a backscattering RF \u2018pixel\u2019 array forming a camera-inspired semi-passive mmID. Two designs consisting of a single lens-based mmID and a multi-lens based mmID. The multi-lens mmID in particular combines both optical lens system design and mmWave antenna design to form a highly detectable mmID with a large solid angle of coverage in the top hemisphere of the mmID. The interrogation of the multi-lens-based mmID was conducted at long ranges and localized accurately even at highly oblique angles of interrogation. The work presented in this thesis present a step forward the creation of future 5G\/mmWave-enabled mmID-based CPSs.\u003C\/p\u003E\r\n","format":"limited_html"}],"field_summary_sentence":[{"value":"High Fidelity Localization of Energy Autonomous mmIDs for Future Cyberphysical Systems "}],"uid":"28475","created_gmt":"2023-11-17 10:49:09","changed_gmt":"2023-11-17 10:51:37","author":"Daniela Staiculescu","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2023-11-21T13:00:00-05:00","event_time_end":"2023-11-21T15:00:00-05:00","event_time_end_last":"2023-11-21T15:00:00-05:00","gmt_time_start":"2023-11-21 18:00:00","gmt_time_end":"2023-11-21 20:00:00","gmt_time_end_last":"2023-11-21 20:00:00","rrule":null,"timezone":"America\/New_York"},"location":"Room 509, TSRB","extras":[],"related_links":[{"url":"https:\/\/teams.microsoft.com\/l\/meetup-join\/19%3ameeting_NmE2MmQwM2YtMDNiZS00ZTViLTg0NmItODEwZTgxNmIxOGI5%40thread.v2\/0?context=%7b%22Tid%22%3a%22482198bb-ae7b-4b25-8b7a-6d7f32faa083%22%2c%22Oid%22%3a%220b3bbb3c-afd1-4c6f-b867-21249926ebb2%22%7d","title":"Microsoft Teams Meeting link"}],"groups":[{"id":"434381","name":"ECE Ph.D. Dissertation Defenses"}],"categories":[],"keywords":[{"id":"100811","name":"Phd Defense"},{"id":"1808","name":"graduate students"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78771","name":"Public"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
