Research Opportunities

Engineering

Work description

1. Identification of the waveguides to be used based on the frequency of interest.

2. Selection of conductive inks and substrates, typical for antennas or alternative ones such as glass, with a focus on sustainable materials and manufacturing techniques suitable for the application.

3. Design (using electromagnetic simulation software) and fabrication of test samples of unit cells of reconfigurable intelligent surfaces, with dimensions appropriate for the selected waveguides.

4. Planning of the experimental setup to support characterization, including the design and fabrication of necessary fixtures for measurements.

5. Performing the experimental characterization of the fabricated test samples using the prepared experimental setups.

6. Implementation in Matlab of data post-processing algorithms required to obtain the electrical parameters of the conductive inks and substrates.

7. Prepare submission of a scientific article.

8. Write the grant activity report.

New research examines how nanoscopic ripples affect material properties

When materials are created on a nanometer scale — just a handful of atoms thick — even the thermal energy present at room temperature can cause structural ripples. How these ripples affect the mechanical properties of these thin materials can limit their use in electronics and other key systems. New research validates theoretical models about how elasticity is scale-dependent — in other words, the elastic properties of a material are not constant, but vary with the size of the piece of material.

In-brief analysis

April 10, 2025

U.S. crude oil exports in 2024 surpassed the previous record set in 2023, exceeding an annual average of 4.1 million barrels per day (b/d). Despite this new record, crude oil export year-over-year growth slowed to 1% in 2024, compared with 14% in 2023 and 21% in 2022.

Crude oil production in the U.S. Lower 48 (L48) states, which does not include Alaska or offshore production, reached a record in November 2024, allowing for a greater supply of crude oil to export. Increased production efficiency counteracted a decrease in the number of active oil rigs, resulting in L48 production increasing 3% last year. Unlike in the L48 states, production in Alaska and offshore in the Gulf of America decreased last year because of natural declines in both areas and because of disruptions to

A new approach to streaming technology may significantly improve how users experience virtual reality and augmented reality environments, according to a new study. The research describes a method for directly predicting visible content in immersive 3D environments, potentially reducing bandwidth requirements by up to 7-fold while maintaining visual quality.
