However, increasing frequencies, decreasing device sizes and more complex materials with highly nonlinear behavior, e.g. superconductors, force simulation engineers to account for more and more spatially resolved effects like wave propagation, eddy-currents, ferromagnetic saturation and hysteresis. Some of these effects can be sufficiently represented by order-reduced models that are embedded in the circuit description. However, in the general case, the coupling of electromagnetic field models and circuit equations is necessary and also well established, see for example the survey article [2].","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124801309","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The existing schemes for transferring signals, based on the conventional materials, are tied to the operation wavelength of the propagating signal and therefore fundamentally limited by it. Moreover, in such schemes the absence of any sort of protection renders them vulnerable to possible defects in the channel, forcing the use of additional elements (for instance filters, amplifiers, etc.) and increasing the overall size and cost of the devices. However, recent developments in the field of artificial media, known as metamaterials [1], showed a great potential for achieving more control over the wave propagation and providing viable solutions for an efficient signal transmission. Unfortunately, since these artificial media consist of resonant inclusions - meta-atoms, they are inherently susceptible to geometrical imperfections and disorder-induced backscattering, which significantly reduces their performance and limits their real applications.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125788932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In real life situations building walls are excited in a random way, making this very similar to what happens inside an electromagnetic reverberation chamber (RC). The paper describes how to measure the SE inside an RC to replicate this real life situation. In particular, cementitious composites are characterized because directly useful for the construction of building walls. The method is based on the using of a nested chamber where the sample is inserted, located inside a larger one to randomly excite the sample.

Namely, this redundancy helps to provide a realistic path to accomplish fundamental support to the symbol decoder, enabling synchronism, access, channel estate estimation, noise and interference removal. In this paper, we study the redundancy that must be added to the radiated symbols in order to facilitate the mentioned physical layer tasks of communication receivers. This paper calls it Radio Frequency Coding (RFC), and with it, the proposal is to systematically review in the non-finite field the different channel coding techniques. Specifically, this paper focuses on linear block RFC. First, it is introduced to support the massive access needs of the future 5th Generation (5G) and to improve the access in the Long Term Evolution (LTE) legacy standard. Second, linear polar coding is proposed to facilitate network slicing, which is one of the most innovative aspects of the 5G architecture.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114674087","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Overall, our system achieves the link power efficiency of −6.6 dB at 7.25 MHz to an implant (2.3-by-2.3 cm square loop) at the center of the abdominal cavity. According to SAR analysis, under the 1.6 W/kg limit, we can transmit 530 mW and the maximum power available at the implant is 149 mW with the voltage amplitude of 3.6 V. Moreover, the voltage at the implant remains above 1 V for transmission power levels down to 10% of the maximum.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"352 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116676986","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a response to the consistent increase in the number of people suffering from various diseases, the medical research is always looking for better diagnostic tools, expedited information transfer technologies, accurate prognosis devices, efficient patient management system and other alternative medicine strategies. In this context, the H2020 Project SINTEC proposes a soft intelligent epidermal communication platform where two main innovations are integrated: soft epidermal electronics and the intra-body communication based on fat tissue as a transmission channel. This proposed platform will host miniaturized, conformal and flexible sensing and data transfer technologies to enable real-time monitoring of certain vital parameters at any time (while doing sport, sleeping or watching television without having to go to a health specialized facility and/or using different devices such as a pulse oximetry, heart rate monitor and thermometer). As part of the phantom development, empirical models relating bioimpedance signals to other physiological signals (ECG, SpO2, Blood Pressure, etc.) is being studied and will be used to optimize phantom-based demonstrators as close as possible to human subjects. To this end, proper characterization of bioimpedance signals in different human subjects is crucial to devise such empirical models. This work presents preliminary results in four human volunteers, with different weight, gender and age, using two types of electrodes configurations. These results show that bioimpedance signals correlate well with volunteer's metadata as predicted by previous works. Finally, the communication through the FAT-channel and also comparisons with the traditional Freespace BLE (Bluetooth Low Energy) protocol will be demonstrated.","PeriodicalId":237030,"journal":{"name":"2019 International Conference on Electromagnetics in Advanced Applications (ICEAA)","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127314253","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
