Photodetector Focal Plane Arrays Integrated with Silicon Micropyramidal Structures in MWIR
Grant W. Bidney, Joshua M. Duran, Gamini Ariyawansa +3
Light-concentrating truncated Si micropyramidal arrays with 54.7 degree sidewall angles were successfully integrated with PtSi Schottky barrier photodetectors. Four different devic…
Focusing and Diffraction of Light by Periodic Si Micropyramidal Arrays
Grant W. Bidney, Amstrong R. Jean, Joshua M. Duran +4
This research was devoted to modeling of the optical properties of Si micropyramids aimed at designing optimal structures for applications as light concentrators in mid-wave infrar…
Level set methods for gradient-free optimization of metasurface arrays
Alex Saad-Falcon, Christopher Howard, Justin Romberg +1
Global optimization techniques are increasingly preferred over human-driven methods in the design of electromagnetic structures such as metasurfaces, and careful construction and p…
Reconfigurable Electromagnetic Structures: X-Band and Beyond
Kenneth W. Allen, Joshua M. Kovitz
Developing reconfigurable millimeter-wave (mmWave) antennas and devices is an outstanding challenge, with switch technologies being a primary impediment. Recently, it has been show…
Aa Unbalanced Feed Design for Wideband Phased Arrays
David W. Landgren, Daniel J. P. Dykes, Kenneth W. Allen
In this work, a planar phased array antenna was engineered with ultra-wideband (UWB) performance that covers portions of the L-, S-, and C-bands. The unit cell design contains a dr…
Whispering gallery mode hybridization in photonic molecules
Yangcheng Li, Farzaneh Abolmaali, Kenneth W. Allen +5
This work takes inspiration from chemistry where the spectral characteristics of the molecules are determined by hybridization of electronic states evolving from the individual ato…
