Information &Functional Materials, Volume 2, Issue 2, Page 118-129, June 2025.A two‐junction 1064 nm VCSEL with double antiresonant oxide islands in the top DBR is designed to enhance fundamental transverse mode operation. By optimizing island count, aperture size, thickness, and position, it achieves 36.2 mW output power, 54.8% PCE, and a 33.06 GHz 3 dB bandwidth.

Attitude stability and altitude control of a variable-geometry Earth-orbiting solar sail [PDF]
, 2016 A variable-geometry solar sail for on-orbit altitude control is investigated. It is shown that, by adjusting the effective area of the sail at favorable times, it is possible to influence the length of the semi-major axis over an extended period of time.

Satellite Data in Agricultural and Environmental Economics: Theory and Practice
Agricultural Economics, Volume 56, Issue 3, Page 493-511, May 2025.ABSTRACT Agricultural and environmental economists are in the fortunate position that a lot of what is happening on the ground is observable from space. Most agricultural production happens in the open and one can see from space when and where innovations are adopted, crop yields change, or forests are converted to pastures, to name just a few examples.
