Among various structures\, the ones with planar form factor are more attractive due to their conformal\, inexp ensive\, and straightforward fabrication process. These microwave/RF senso rs operate based on the perturbation of the electromagnetic (EM) field and the interaction of the EM field with materials in their close vicinity. C onventionally\, these microwave/RF sensors have been fabricated using meta l traces and microstrip lines which gives good microwave response and beha vior for those sensors monitoring dielectric properties of solid and liqui d materials. However\, microwave/RF sensor applications were limited in ex posure to gas molecules due to their negligible sensitivities to gas molec ules. To address this challenge\, secondary materials such as polymers\, n anomaterials such as carbon nanotubes and titanium nanotubes\, and recentl y titanium carbide (MXene) were introduced to act as an interface layer to enable gas sensing and even light sensing directly at microwave frequenci es. This lecture will mainly focus on different planar microwave/RFID-base d structures and their interactions with nanomaterials such as TiO2 nanotu bes\, mesoporous metal-organic frameworks (MOFs)\, and MXene in exposure t o gas molecules and water vapors. Moreover\, conductive polymers such as P EDOT:PSS will be discussed in microwave structures as an alternative to me tals in microstrip lines to eliminate the use of extra interface materials for monitoring gases. In addition\, the potential of 3D printing and othe r additive manufacturing techniques will be discussed in the nanomaterials concept to empower the microwave/RFID-based sensors.\n\nCo-sponsored by: Wayne Shiroma\n\nSpeaker(s): Dr. Zarifi\n\nVirtual: https://events.vtools. ieee.org/m/481486 LOCATION:Virtual: https://events.vtools.ieee.org/m/481486 ORGANIZER:marahman@hawaii.edu SEQUENCE:8 SUMMARY:Microwave/RF Devices and their Interactions with Novel Nano-Materia ls for Sensing and Communication Applications URL;VALUE=URI:https://events.vtools.ieee.org/m/481486 X-ALT-DESC:Description: <br /><p class="MsoNormal"><strong style="mso-bidi- font-weight: normal\;"><span style="font-size: 11.5pt\; font-family: 'Aria l'\,sans-serif\;">Abstract</span></strong></p>\n<p>Microwave and Radio Fre quency devices have demonstrated significant potential in non-destructive\ , non-ionizing\, contactless\, and wireless sensing applications.
