This paper proposes a pixel antenna, designed for mid-infrared frequencies with a bandwidth more than 25 THz, consisting of 3 × 3 square metallic planar patches. Bolometer-based switches are placed between the adjacent pixels in order to obtain the adaptable characteristics, optimized for the incoming infrared radiation. The incident wave from a certain direction will heat up the bolometers. Consequently, the conductivity of these bolometers (PTC) will be decreased, and as a result they can be considered to turn to OFF state. The simulation results suggest that the proposed structure can steer the antenna pattern toward the direction of the incident radiation in an adaptable manner, thereby considerably increasing the antenna gain. The gain of the antenna can be increased up to 2 dB with respect to the reference one, which makes it a promising structure for various applications.}, year = {2022}, eissn = {1424-8220} } @article{MTMT:32778062, title = {A Fluorescent Protein-Based OR Gate for Photon-Coupled Protein Logic}, url = {https://m2.mtmt.hu/api/publication/32778062}, author = {Rakos, Balázs}, doi = {10.1007/978-981-19-0379-3_6}, journal-iso = {LNNS}, journal = {LECTURE NOTES IN NETWORKS AND SYSTEMS}, volume = {422}, unique-id = {32778062}, issn = {2367-3370}, year = {2022}, eissn = {2367-3389}, pages = {53-58} } @inproceedings{MTMT:34689516, title = {A pixelized infrared antenna design}, url = {https://m2.mtmt.hu/api/publication/34689516}, author = {Shubbar, Mustafa and Rakos, Balázs}, booktitle = {Proceedings of the Automation and Applied Computer Science Workshop 2021}, unique-id = {34689516}, year = {2021}, pages = {60-68} } @inproceedings{MTMT:34689924, title = {An Optimized Patch Antenna for Infrared Energy Harvesting}, url = {https://m2.mtmt.hu/api/publication/34689924}, author = {Shubbar, Mustafa and Rakos, Balázs}, booktitle = {Proceedings of the Automation and Applied Computer Science Workshop 2020}, unique-id = {34689924}, year = {2020}, pages = {53-60} } @article{MTMT:31451542, title = {Modeling and simulation of photon-coupled, fluorescent photoswitchable protein logic}, url = {https://m2.mtmt.hu/api/publication/31451542}, author = {Rakos, Balázs}, doi = {10.1002/cta.2861}, journal-iso = {INT J CIRC THEOR APP}, journal = {INTERNATIONAL JOURNAL OF CIRCUIT THEORY AND APPLICATIONS}, volume = {48}, unique-id = {31451542}, issn = {0098-9886}, abstract = {Today's society has an ever-increasing demand for smaller-scale, lower-energy-consuming, cheaper, and faster computing and digital signal processing systems. Photon-coupled, fluorescent photoswitchable protein-based architectures are promising candidates for the fulfillment of these requirements. In order to properly design digital circuits based on the aforementioned building blocks, an efficient simulation procedure is needed. We present a simple, differential equation-based model, suitable for the design and simulation of such structures. It characterizes the radiation-induced switching, the form-dependent fluorescence, and the effect of photon coupling in a fast and efficient manner. The applicability of the model is demonstrated through simulations of the OR and NOR logic gates consisting of readily available, fluorescent photoswitchable proteins. It can be a potential design tool for future molecular logic circuitry based on such molecules.}, keywords = {Molecular electronics; Logic circuits; nanoelectronics; Organic electronics; Protein modeling; photon coupling; photoswitchable protein}, year = {2020}, eissn = {1097-007X}, pages = {2130-2140} } @article{MTMT:31134923, title = {Photon-Coupled, Two-State Photoswitchable Protein-Based Multiple-Valued Logic}, url = {https://m2.mtmt.hu/api/publication/31134923}, author = {Rakos, Balázs}, doi = {10.1007/978-3-030-36841-8_13}, journal-iso = {LNNS}, journal = {LECTURE NOTES IN NETWORKS AND SYSTEMS}, volume = {101}, unique-id = {31134923}, issn = {2367-3370}, year = {2020}, eissn = {2367-3389}, pages = {129-134} } @article{MTMT:31006464, title = {Multiple-valued computing by dipole-dipole coupled proteins}, url = {https://m2.mtmt.hu/api/publication/31006464}, author = {Rakos, Balázs}, doi = {10.1002/cta.2649}, journal-iso = {INT J CIRC THEOR APP}, journal = {INTERNATIONAL JOURNAL OF CIRCUIT THEORY AND APPLICATIONS}, volume = {47}, unique-id = {31006464}, issn = {0098-9886}, year = {2019}, eissn = {1097-007X}, pages = {1357-1369} }
