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…
Label-Free Nanoscopy with Contact Microlenses: Super-Resolution Mechanisms and Limitations
Vasily N. Astratov, Farzaneh Abolmaali, Aaron Brettin +5
Despite all the success with developing super-resolution imaging techniques, the Abbe limit poses a severe fundamental restriction on the resolution of far-field imaging systems ba…
iQ Cavity for Material Permittivity Characterization
Kenneth W. Allen, Mark M. Scott
We present an X-band waveguide (WR90) and UHF waveguide (WR1500) measurement method that permits the extraction of the complex permittivity for low dielectric loss tangent material…
An X-Band Waveguide Measurement Technique for the Accurate Characterization of Materials with Low Dielectric Loss Permittivity
Kenneth W. Allen, Mark M. Scott, David R. Reid +4
In this work, we present a new X-band waveguide (WR90) measurement method that permits the broadband characterization of the complex permittivity for low dielectric loss tangent ma…
