Fabrication of phononic filter structures for far-IR/sub-mm detector applications
Kevin L. Denis, Karwan Rostem, Marco A. Sagliocca +2
A photon noise limited sub-mm/far-IR cold telescope in space will require detectors with noise equivalent power (NEP) less than 1x10-19 W/Hz1/2 for imaging applications and at leas…
Robust Modeling of Acoustic Phonon Transmission in Nanomechanical Structures
John Bartlett, Karwan Rostem, Edward Wollack
The transmission of acoustic phonons is an important element in the design and performance of nano-mechanical devices operating in the mesoscopic limit. Analytic expressions for th…
SOFIA - HIRMES: Looking forward to the HIgh-Resolution Mid-infrarEd Spectrometer
Samuel N. Richards, Samuel H. Moseley, Gordon Stacey +48
The HIgh-Resolution Mid-infrarEd Spectrometer (HIRMES) is the 3rd Generation Instrument for the Stratospheric Observatory For Infrared Astronomy (SOFIA), currently in development a…
On-sky performance of the CLASS Q-band telescope
John W. Appel, Zhilei Xu, Ivan L. Padilla +34
The Cosmology Large Angular Scale Surveyor (CLASS) is mapping the polarization of the Cosmic Microwave Background (CMB) at large angular scales () in search of a…
Dielectric Properties of Conductively Loaded Polyimides in the Far Infrared
Kyle R. Helson, Kevin H. Miller Karwan Rostem, Manuel Quijada +1
The dielectric properties of selected conductively-loaded polyimide samples are characterized in microwave through far infrared wavebands. These materials, belonging to the Vespel\…
A 3D-printed broadband millimeter wave absorber
Matthew Petroff, John Appel, Karwan Rostem +5
We present the design, manufacturing technique, and characterization of a 3D-printed broadband graded index millimeter wave absorber. The absorber is additively manufactured using…
