2023 IEEE MTT-S
International Microwave Symposium
San Diego, CA, USA
June 11-16, 2023

Conference website: https://ims-ieee.org
QWED will participate in the IEEE MTT-S International Microwave Symposium in San Diego, USA and in the exhibition.
In addition to the presentations and workshops, QWED will also have an exhibition booth #2537 located near the MicroApps Theater at IMS 2023. The exhibition site will serve as a platform to showcase our innovative products, solutions, and technologies in the field of microwave engineering. Attendees will have the opportunity to interact with our representatives, and explore the latest advancements in microwave-related offerings from QWED.
During the conference, QWED will be presenting and conducting workshops on various topics. Here is a list of events where we will showcase our work:

QWED Presentation WMH-4 "Emerging Applications of Microwave Resonators to Energy- and Bio-Based Materials Under Extended Temperature and Humidity Ranges"

IMS Industry Workshop IWWE6
Title: mmWave Permittivity Standard Reference Material Development
Date: Wednesday, 14 June
Time: 13:30 - 15:10
Speakers: Say Phommakesone, Lucas Enright, Marzena Olszewska-Placha, Urmi Ray
Location: 29D
Abstract:
Workshop discusses results of iNEMI 5G/mmWave project on developing permittivity standard reference material (SRM), allowing industry for calibrating high frequency dielectric characterization tools spanning 10 to 120 GHz. SRM candidates are tested with industry acknowledged material characterization techniques within round-robin routine involving 8 laboratories worldwide. Testing results support development of traceable reference sample. Consortium efforts are in parallel directed to developing roadmap on 5G/6G materials and electrical test technology. Workshop comprises four presentations (5G industry needs and project goals, standardization efforts for traceable material standard, round-robin results, roadmapping efforts) supported with hands-on exercises (involving Keysight and QWED equipment, NIST SRM candidates).

MicroAPPS Seminar
Date: Tuesday, 13 June
Time: 14:30 - 14:45
Location: MicroApps Theater, Booth 2447
QWED Presentation TUMA21: "Dielectric and Cavity Resonators for Accurate Characterization of Liquids in the 1-50 GHz Frequency Range"
Speaker: Marzena Olszewska-Placha
Abstract
Discover high-precision material characterization techniques for low-loss coolant liquids used in high-frequency electronics immersion. Explore a range of measurement fixtures, including dielectric resonators and a Fabry-Perot open resonator, designed to accurately and reliably characterize liquids across a wide frequency bandwidth. Don't miss the opportunity to learn about complex permittivity measurements and the impact of temperature variations on dielectric and cavity resonators.

Date: Tuesday, 13 June
Time: 15:00 - 15:15
Location: MicroApps Theater, Booth 2447
QWED Presentation TUMA23: "A New Non-Destructive Microwave Technique for Quantitative Testing of Large-Scale Panels of Graphene-based Polymer Composites for EMI Applications"
Speaker: Malgorzata Celuch
Abstract
Shielding properties of graphene-based polymer composites (GBPC) are enhanced by uniform dispersion of graphene flakes within the polymer matrix. Little attention has been given thus far to the rigorous studies of spatial inhomogenetities of the electrical and dielectric properties of GBPCs, due to nonuniform filler distribution in practical fabrication. We present:
- A microwave technique producing 2D quantitative maps of resistivity of GBPCs; QWED's 2D dielectric-resonator-based scanner is applied.
- Experimental results for large (10cm x 10cm) GBPC panels, demonstrating a tremendous effect of the fabrication process parameters on inhomogeneities of the resistivity, which degrade the shielding efficiency.
We also invite you to the session presenting results from QWED collaborators:
