Special Issue Information

Dear Colleagues,

It is well know that the origin of Quantum Theory comes from Max Planck (1900) through his celebrated formulation of the radiation spectral density as frequency and temperature functions of a blackbody ideal concept, using the Boltzmann´s probabilistic interpretation of entropy. After that, the mathematical theory of information and communications was established (Shannon, 1949) by statistical explanations and predictive dynamics. Today, new engineering fields are established with emerging developments: quantum computing, sensor and actuator networks (IoT), robotic machines, adaptive structural materials, etc. All these complex systems require recent and innovative technologies supported by optical and quantum electronic–OQE-components and devices. The incidence of this actual evolution is global, and there are many different affected fields: energy, automotive and mobility, autonomous drive systems, biomedicine and neurosciences, environment actions, Earth sciences, manufacture industry and business, social and economic, etc.

This requires us to enable managed development, and this managed development requires general supports on which to base its decisions: the analysis of optical and quantum electronic systems by statistical thermodynamic turns out to be an excellent method for it. This Special Issue is a call to focus our effort on entropy, information theory of optical and quantum electronics complex systems: lidars, attenuators, couplers, multi/demulti-plexers, omnidirectional stereo and hyperspectral cameras, micro and nano electromechanical systems, and other components, that could be analyzed in efficiency and/or performances by this way. Additionally, these would be relevant to be applied on the development of renewable energy systems, new logical interface human-chips, or in environmental prevention sensors.

It would be fundamental to extend this statistical thermodynamic analysis to the new quantum metrological standard.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Entropy is an international peer-reviewed open access monthly journal published by MDPI.

This article introduces a novel Ultra Wide Band (UWB) Multiple Input Multiple Output (MIMO) antenna with Triple-band notched characteristics. The overall dimensions of the antenna are 18 × 34 mm2. The designed antenna has two similar flower-shaped radiators with L-shape strips, common ground with two flag-shaped decoupling stubs and T-shape strips for notched band characteristics. Two flag-shaped stubs are used to achieve 22 dB improved isolation. The S11 of the designed antenna is less than −10 dB between 3.07 GHz and 12.40 GHz, having various stopped bands of WiMAX, WLAN and X bands. The presented antenna is examined and investigated in terms of S-parameters, Mutual Coupling, Gain, Envelope Correlation Coefficient (ECC), Efficiency and Diversity Gain (DG). Full article
