SI2 Trap Shooting Team supports the Light Foundation

Recently the Light Foundation held their annual Celebrity Shoot out and fund raiser. An SI2 Foursome competed in the shootout, as well as live and silent auctions.

The Light Foundation's response was high praise. "We can't thank you enough! This year's Shoot-Out celebrated 15 Years of The Light Foundation, 15 Years of unmatched support from our donors and 15 Years of creating young leaders through outdoor programming. In light of that celebration, we raised nearly $800,000 for the Light Foundation to expand our reach and further impact the lives of young men and women for years to come! In the pouring rain, our supporters, donors and sponsors showed up to was our largest and most successful event EVER.

SI2 is proud to support local charities, and to be counted as one of the Light Foundation's strong supporters.

SI2 Technologies at NextFlex Innovation day

Recently, Charter Member SI2 Technologies, Inc. presented on flexible hybrid electronics (FHE) and antennas at the NextFlex Consortium Innovation Day 2018. This by invitation only event was held at the NextFlex headquarters in San Jose, CA. The Third Annual Innovation Day represented a “Who’s Who in FHE” from NextFlex members, subject-matter experts, government partners, and dignitaries, with over 300 people celebrating how NextFlex and its 85 members around the country are delivering on the promise of “electronics on everything.” Speakers and guests included local political leaders, CTO from Defense Prime contractors, and NextFlex members and innovators.

As the first consortium member to join NextFlex, SI2 Technologies proudly displayed some of the latest innovations at the leading edge of an intersection between FHE and custom antennas. Douglas Kern, Ph.D., presented on the attached video.

SI2 Technologies, Inc. supports Air Force Research Laboratory Munitions Directorate

Amanda Schrand, Ph.D, of the Air Force Research Laboratory Munitions Directorate, conducts the out brief of the week long sprint technology development to representative customers

SI2 was one of two small businesses invited to join the week long Technology Sprint by AFRL Munitions Directorate at the Doolittle Institute in Niceville, FL recently. Under the global heading of Designing Resilient Hybrid Technologies, the week's specific task was "Resilient Hybrid Electronics Technology Sprint: 3D Printed Conformal Antenna." Along with diverse government organizations and universities, SI2 brought extensive additive manufacturing and antenna/Flexible Hybrid Electronics experience to the working event. The sprint is a week-long team technology design event based on this book that takes a problem from inception to customer testing in just one week.

During this week, the group examined a real world munitions need, the technologies and potential solutions to address it, and fabricated a prototype which was briefed to the representative customers.

SI2 is a specialty RF company specializing in antenna, array, and sensor designs using both conventional and additive manufacturing.

SI2 Technologies, Inc. Participates in 2018 National Security Innovation Summit (NSIS)

From July 16-July 18th, SI2 participated in the NSIS conference for small businesses on the forefront of innovative technologies. The conference is for invited presentations only, and SI2 presented on the seven generations of Tightly Coupled Dipole Arrays produced for various customers since 2008. The conference included meetings with Chief Technology Officers and the equivalents from the USASMDC, DHS, DTIC, and the APEO Future Operations for Army PEO Aviation. Highlights of the multi-day event were urgent needs briefings from all US Combatant Commands.

Additive Manufacturing of Radio Frequency Systems

SI2 Technologies, Inc. is leveraging its experience with RF design and additive manufacturing (AM) to design, 3D-print, and range-test novel phased array antennas and related systems. Our team is developing printed, high-efficiency phased arrays operating at DoD-relevant frequencies. These electronically-steerable phased arrays have no moving parts (increasing long-term reliability) and can survive the failure of individual array elements with manageable performance degradation. Conventional methods of manufacturing arrays with complex architectures can be costly, whereas SI2’s additively manufactured arrays are well-suited for size-, weight-, power-, and cost-constrained applications. In the past, the integration of multiple material classes (e.g., dielectrics and electrical conductors) into a single AM build has been a challenge due to materials and processing incompatibilities. We detail how to overcome these challenges by 1) utilizing a 3D printer that can print FDM filaments, print conductive pastes, and mill surfaces and 2) optimizing the chemistries between dissimilar materials. We will include trade studies to identify the best printing technique or combination of techniques to meet the DoD’s phased array performance goals. This approach minimizes production costs, array volume, and thermal management issues, and maximizes array efficiency. We will detail the considerable experience with printed electronics, phased array antenna design, and phased array antenna fabrication and testing. Commercial applications for these arrays include low cost antennas and arrays for weather monitoring, air traffic control, maritime vessel traffic control, and vehicle speed detection for law enforcement. An overview of AM phased array work will be presented.

Learning Objectives:

  • Describe how to build a 3D printed array using multiple techniques.
  • Describe how the printing process affects the performance of the array.
