Analytical Modeling of a Two-Dimensional Waveguide-Fed Metasurface
Laura Pulido-Mancera, Mohammadreza F. Imani, Patrick T. Bowen +2
We develop a fast, accurate, and robust technique to model the electromagnetic response of a two-dimensional (2D) waveguide-fed metasurface aperture. The geometry under considerati…
Analysis of a Waveguide-Fed Metasurface Antenna
David R. Smith, Okan Yurduseven, Laura Pulido Mancera +2
The metasurface concept has emerged as an advantageous reconfigurable antenna architecture for beam forming and wavefront shaping, with applications that include satellite and terr…
Polarizability Extraction for Waveguide-Fed Metasurfaces
Laura Pulido-Mancera, Patrick T. Bowen, Nathan Kundtz +2
We consider the design and modeling of metasurfaces that couple energy from guided waves to propagating wavefronts. This is a first step towards a comprehensive, multiscale modelin…
Electron-mediated ferromagnetism and small spin-orbit interaction in a molecular-beam-epitaxy grown n-type heterostructure with Mn -doping
A. Bove, F. Altomare, N. B. Kundtz +4
We report the first evidence of electron-mediated ferromagnetism in a molecular-beam-epitaxy (MBE) grown heterostructure with Mn -doping. The interacti…
A novel technique to make Ohmic contact to a buried two-dimensional electron gas in a molecular-beam-epitaxy grown heterostructure with Mn -doping
A. Bove, F. Altomare, N. B. Kundtz +4
We report on the growth and characterization of a new Diluted Magnetic Semiconductor (DMS) heterostructure that presents a Two-Dimensional Electron Gas (2DEG) with a carrier densit…
Spin dependent resonant tunneling through 6 micron diameter double barrier resonant tunneling diode
Z. L. Fang, P. Wu, N. Kundtz +3
A vertical resonant tunneling diode (RTD) based on the paramagnetic Zn1-x-yMnyCdxSe system has been fabricated with a pillar diameter down to ~ 6 micron. The diode exhibits high qu…
