Directionality fields generated by a local Hilbert transform
(American Physical Society, 2018-03-15)
We propose an approach based on a local Hilbert transform to design non-Hermitian potentials generating arbitrary vector fields of directionality, p→(r→), with desired shapes and topologies. We derive a local Hilbert ...
Robust Temperature Control of a Thermoelectric Cooler via -Synthesis
(Springer New York LLC, 2018)
In this work robust temperature control of a thermoelectric cooler (TEC) via -synthesis is studied. An uncertain dynamical model for the TEC that is suitable for robust control methods is derived. The model captures ...
Maximizing Wireless Sensor Network lifetime by communication/computation energy optimization of non-repudiation security service: Node level versus network level strategies
(Elsevier Science Bv, 2016-02)
In a typical Wireless Sensor Network (WSN) application, the basic communication service is the transportation of the data collected from sensors to the base station. For prolonging the network lifetime, energy efficiency ...
A reduced symmetric 2D photonic crystal cavity with wavelength tunability
(Institute of Physics Publishing, 2019)
In this paper, we propose a microcavity supported by a designed photonic crystal structure that provides both tunability of cavity modes and the cavity's quality factor. A low symmetric defect region provides a trigger ...
Invisibility on demand based on a generalized Hilbert transform
(American Physical Society, 2018-07-12)
We propose a feasible invisibility approach to suppress the scattering of waves from or to given directions and for particular frequencies, i.e., invisibility on demand. We derive a generalized Hilbert transform for a ...
Disturbance/Uncertainty Estimator Based Robust Control of Nonminimum Phase Systems
(Institute of Electrical and Electronics Engineers Inc., 2018-08)
An open problem in disturbance/uncertainty estimator based control is to obtain explicit mathematical expressions for robust stability, performance, and bandwidth requirement. This paper offers a path based on H-infinity ...
Full utilization of semi-Dirac cones in photonics
(American Physical Society, 2018-05-16)
In this study, realization and applications of anisotropic zero-refractive-index materials are proposed by exposing the unit cells of photonic crystals that exhibit Dirac-like cone dispersion to rotational symmetry reduction. ...
Multipath exploitation for knowledge-aided adaptive target detection
(Institution of Engineering and Technology, 2019)
The authors consider the problem of multipath exploitation on adaptive radar detection of point-like targets in a multipath environment where a priori information is available. A new approach to exploit multipath returns ...
The Impact of Incomplete Secure Connectivity on the Lifetime of Wireless Sensor Networks
(Institute of Electrical and Electronics Engineers Inc., 2018-03)
Key predistribution schemes accommodate secure connectivity by establishing pairwise keys between nodes. However, ensuring security for all communication links of a wireless sensor network (WSN) is nontrivial due to the ...
Scheduled smooth MIMO robust control of aircraft verified through blade element SIL testing
(SAGE Publications Ltd, 2018-01-01)
This paper demonstrates a multi-input multi-output (MIMO) robust control approach where multiple scheduled designs are merged to produce a smooth control law. The design is verified using software-in-the-loop (SIL) testing ...
