Silicon-based terahertz (THz) integrated circuits (ICs) have made rapid progress over the
past decade. The demonstrated basic component performance, as well as the maturity of …

Volatile organic compounds are released by different sources causing air pollution.
Moreover, some of these carbon-based organic chemicals are considered as biomarkers in …

Context. Urea, NH 2 C (O) NH 2, is a molecule of great importance in organic chemistry and
biology. Two searches for urea in the interstellar medium have been reported in the past, but …

Breath gas analysis is a promising tool for medical research and diagnosis. A particularly
powerful technological approach is millimeter-wave/terahertz (mmW/THz) spectroscopy …

CMOS IC technology has become an affordable means for implementing capable systems
operating at 300 GHz and above. CMOS circuits have been used to generate a signal up to …

Although heretofore unrealized, it has long been known the rotational fingerprints of gases
that occupy the submillimeter/terahertz (SMM/THz) spectral region can provide a basis for …

The unique fingerprint spectra of volatile organic compounds for breath analysis and toxic
industrial chemicals make an mm-wave (mmW)/THz gas sensor very specific and sensitive …

The definition for the frequency range of a terahertz wave varies in the literature. Some refer
to terahertz as the spectrum between 300 GHz (λ= 1 mm) and 3 THz (λ= 0.1 mm) to …

This paper describes the design and implementation of a 220-320 GHz spectrometer
consisting of a pair of 65-nm CMOS chips. The spectrometer utilizes two counterpropagating …

Chirped-pulse Fourier transform spectroscopy has recently been extended to millimeter
wave spectroscopy as a technique for the characterization of room-temperature gas …
