Antenna-coupled TES bolometers used in BICEP2, Keck array, and SPIDER

open access: yes, 2015
We have developed antenna-coupled transition-edge sensor (TES) bolometers for a wide range of cosmic microwave background (CMB) polarimetry experiments, including BICEP2, Keck Array, and the balloon borne SPIDER. These detectors have reached maturity and

Time domain analysis of a wideband common-mode suppression filter for bent interconnects [PDF]

open access: yes, 2011
A technique to efficiently reduce differential-to-common mode conversion occuring at a bend discontinuity in coupled microstrip lines is investigated. Total signal integrity in the interconnect structure has been improved by minimizing the differential ...

Enhanced Responsivity, Accuracy, and Stability of Aerosol Jet Printing via Mechanical Switching Valve Assisted Internal Shuttering

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
This work demonstrates ultra‐high ON‐OFF responsivity of AJP by mechanical switching valve assisted shuttering. The jet relaxation and ON‐OFF delay are substantially eliminated from greater than 35 s, maintaining patterning quality independent of the variations of printing parameters, permitting excellent process stability and universality.

Dual-mode dual-band microstrip filters

open access: yes2009 European Microwave Conference (EuMC), 2009
A compact dual-band microstrip bandpass filter is proposed using dual-mode resonators. Two microstrip loop resonators, one within the other, are employed to obtain dual-mode dual-band filter responses. Each loop resonator uses two loading elements to excite dual modes.
