Evaluation of the Performance of the Distributed Phased-MIMO Sonar

Sensors, 2017
A broadband signal model is proposed for a distributed multiple-input multiple-output (MIMO) sonar system consisting of two transmitters and a receiving linear array.

Adaptive polarization separation [PDF]

, 1981
A broadband adaptively controlled polarization separation network is discussed. Two transmitted signals vertically and horizontally polarized are received as elliptically polarized signals.

Broadband Microwave Correlator of Noise Signals

Metrology and Measurement Systems, 2010
Broadband Microwave Correlator of Noise SignalsA real narrowband noise signal representation in the form of an analytical signal in the Hilbert space is presented in the paper. This analytical signal is illustrated in a variable complex plane as a mark with defined amplitude, phase, pulsation and instantaneous frequency.

Modulating Two‐Photon Absorption in a Pyrene‐Based MOF Series: An In‐Depth Investigation of Structure–Property Relationships

Advanced Functional Materials, EarlyView.
This study investigates H4TBAPy‐based metal–organic frameworks (MOFs) ‐ NU‐1000, NU‐901, SrTBAPy, and BaTBAPy ‐ for multiphoton absorption (MPA) performance. It observes topology‐dependent variations in the 2PA cross‐section, with BaTBAPy exhibiting the highest activity.

A single-beam spoof surface plasmon polariton leaky-wave antenna with backfire radiation and wide-angle scanning capability

Materials & Design
A single-beam spoof surface plasmon polariton (SSPP) leaky-wave antenna (LWA) with backfire radiation and wide-angle scanning capability is proposed. In the antenna structure, a Goubau line (GL) with a periodic open ring array etching is specifically ...

CREATION OF PSEUDO-RANDOM SEQUENCES BASED ON CHAOS FOR FORMING OF WIDEBAND SIGNAL

Information and Telecommunication Sciences, 2017
Background. Telecommunication systems with a broadband signal have improved noise immunity, the ability to receive a signal in multipath, as well as electromagnetic compatibility with neighboring radio electronic devices.

A non-invasive, quantitative study of broadband spectral responses in human visual cortex. [PDF]

PLoS ONE, 2018
Currently, non-invasive methods for studying the human brain do not routinely and reliably measure spike-rate-dependent signals, independent of responses such as hemodynamic coupling (fMRI) and subthreshold neuronal synchrony (oscillations and event ...

Broadband phased array antenna steering by means of coherent signal combining in an integrated ring resonator-based optical beamformer [PDF]

, 2008
A squint-free, continuously tunable optical beamformer for broadband phased array receive antennas is proposed. The complete system is demonstrated, including E/O and O/E conversions, and optical signal processing.

Single-photon-level light storage in cold atoms using the Autler-Townes splitting protocol

, 2019
Broadband spin-photon interfaces for long-lived storage of photonic quantum states are key elements for quantum information technologies. Yet, reliable operation of such memories in the quantum regime is challenging due to photonic noise arising from ...

Broadband signal processing in communication systems [PDF]

The Journal of the Acoustical Society of America, 1983
The broadband characteristics of the underwater acoustic propagation channel determine both the approach to communicating and the performance which can be achieved. This paper presents a detailed broadband characterization of the channel and uses this characterization to describe approaches to communication.
