Vector Network Analyzer Calibration for Quasi-Optical Dual Ports

Goddard Space Flight Center, Greenbelt, Maryland It is desirable to measure the electromagnetic properties of devices and materials in the millimeter part of the spectrum. For guided wave-based devices and materials (waveguides, coaxial devices), a vector network analyzer (VNA) is an excellent tool for this purpose since it provides full reflection and transmission characterization at high precision.

Optically Modulated Miniature Magnetometer

This instrument may replace two separate instruments that are often needed together to study magnetic fields. Goddard Space Flight Center, Greenbelt, Maryland The optically modulated miniature magnetometer (OMMM) is intended to replace two separate instruments (each with their respective mass and power allotments) that are commonly needed together for scientific studies of magnetic fields — a triaxial fluxgate vector magnetometer and an optically pumped alkali vapor scalar magnetometer. For all vector instruments, the scalar data is necessary for calibrating the vector data.

Assisting An Aging Population: Designing Medical Devices With Force Sensing Technology

With the geriatric population on the rise, design engineers are challenged with designing responsive, noninvasive, user-friendly medical devices that cater to the needs of an older generation. Patients are looking for cost-effective, easy to use assistive tools that help them regain independence and confidence in their everyday life. Force feedback is a key feature for many of these devices that provide the user and doctor with great insight that ultimately results in better quality of life for the patient. Medical devices with force feedback allow design engineers to create innovative products that differentiate them from the competition.

Multiphysics Flow Simulations

Computational fluid dynamics (CFD) is often included in multiphysics analyses as a way to understand fluid flow, as well as being the convective mode for other physics. In this webinar, we will explain how to simulate CFD applications in COMSOL Multiphysics® including laminar, turbulent, and multiphase flows interacting with structures (FSI). We will also examine mass transport, electromagnetics, and heat transfer.

Quantitative Analysis of Failure Mode in Adhesively Bonded Test Specimens

A fluorescence visualization technique is used. Langley Research Center, Hampton, Virginia After adhesively bonded mechanical test specimens have been tested to failure, the failure mode must be interpreted and quantified. Areas of the adherent that are bare (no residual adhesive remains) have undergone adhesive failure. The remainder of the surface has undergone cohesive failure. The ability to distinguish and accurately quantify the relative amounts of cohesive and adhesive failure on a failed bonding surface is of tremendous importance in the field of mechanical testing, and for the development of bonded assemblies. Some adhesives (and adherents) are fluorescent, meaning they re-emit light at a different wavelength after being irradiated by some lighting source. This property allows for quantitative analysis of the adhesive failure mode (adhesive and cohesive). A digital image of the fluorescing adhesive or adherent can be analyzed and quantified using publicly available software to determine the relative areas of exposed and covered adherent surface.
