New Concept of Combined Microwave Delay Lines for Noise Radar-Based Remote Sensors
Sensors, 2019 Delay lines with a tunable length are used in a number of applications in the field of microwave techniques. The digitally-controlled analogue wideband delay line is particularly useful in noise radar applications as a precise detector of movement.

Interpreting broad emission-line variations I : Factors influencing the emission-line response
, 2014 We investigate the sensitivity of the measured broad emission-line responsivity dlog f_line/dlog f_cont to continuum variations in the context of straw-man BLR geometries of varying size with fixed BLR boundaries, and for which the intrinsic emission ...

Theory of Synthesis of Asymmetrical Delay Line with the Surface Acoustic Wave
Archives of Acoustics, 2019 The aim of this publication is to design a procedure for the synthesis of an IDT (interdigital transducer) with diluted electrodes. The paper deals with the surface acoustic waves (SAW) and the theory of synthesis of the asymmetrical delay line with the ...

Antenna-coupled millimeter-wave LiNbO_3 electro-optic modulator [PDF]
, 1991 The phase-velocity mismatch due to material dispersion in traveling-wave LiNbO_3 optical waveguide modulators may be greatly reduced by breaking the modulation transmission line into short segments and connecting each segment to its own surface antenna.

Time Delay Measurement of Mg ii Line in CTS C30.10 with SALT [PDF]
Astrophysical Journal, 2019 We report 6 yr monitoring of distant bright quasar CTS C30.10 (z = 0.90052) with the Southern African Large Telescope. We measured the rest-frame time lag of days between the continuum variations and the response of the Mg ii emission line, using six ...

On the Influence of Delay Line Uncertainty in THz Time-Domain Spectroscopy [PDF]
, 2016 Terahertz time-domain spectroscopy (THz TDS) is a well-known tool for material analysis in the terahertz frequency band. One crucial system component in every time-domain spectrometer is the delay line which is necessary to accomplish the sampling of the
