The Soil Moisture Active-Passive (SMAP) L-band microwave radiometer is a conical
scanning instrument designed to measure soil moisture with 4% volumetric accuracy at 40-km …

This paper describes frequency scanning slot arrays operating from 130 to 180 GHz. The
arrays are micro-fabricated using the PolyStrata sequential copper deposition process. …

This paper presents several micro-coaxial broadband 2 : 1 Wilkinson power dividers operating
from 2 to 22 GHz, a 11 : 1 bandwidth. Circuits are fabricated on silicon with PolyStrata …

This paper demonstrates two broadband air-filled micro-coaxial 4:1 (2-24 GHz) and 2.25:1 (2-22
GHz) impedance transformers. The 4:1 transformer converts 50 to 12.5 Ω and the 2.25:1 …

This paper discusses fundamental properties of rectangular micro-coaxial lines fabricated in
the PolyStratatrade process for broadband applications from 2-20 GHz. The possible …

The experiment for cryogenic large-aperture intensity mapping (EXCLAIM) is a balloon-borne
telescope designed to survey star formation in windows from the present to z = 3.5. During …

Micro-Spec is a direct-detection spectrometer which integrates all the components of a
diffraction-grating spectrometer onto a ≈ 10 -cm 2 chip through the use of superconducting …

Beam steering antenna arrays have many applications, from object tracking and localization
to landing systems [1]. The main requirements for such a system are usually a wide …

In this work, a rectangular coaxial transmission line based power amplifier is discussed. This
transmission line is created by sequential photolithography and plating processes, resulting …

The EXperiment for Cryogenic Large-aperture Intensity Mapping (EXCLAIM) is a cryogenic
balloon-borne instrument that will map carbon monoxide and singly-ionized carbon emission …
