Using photonic systems makes it possible to generate and detect signals in the complete frequency range. To measure amplitude and phase with so-called time domain spectroscopy (TDS) systems usually requires the acquisition and Fourier analysis of complete pulse transients. Simplifying this process helps to design systems which allow for fast scanning in the THz range. We modified a commercial TDS system with a two-channel lock-in amplifier and a bandpass filter in the range of 800-900GHz to completely remove the post processing which is necessary to acquire phase and amplitude information. In this paper we present a system which reduces the acquired data to two output parameters for amplitude and phase which can be measured at the same time. This makes precise and fast measurements of phase objects at a target frequency possible. This is shown by acquiring a qualitative phase image of a technical sample.","PeriodicalId":267901,"journal":{"name":"2018 First International Workshop on Mobile Terahertz Systems (IWMTS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129733233","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}

Terahertz (THz) band offers bandwidth orders of magnitude greater than the lower-frequency communications; however, this band has different prorogation mechanisms influencing a wireless transmission compared to the lower frequency bands. The bandwidth of transmission at THz band is highly distance-dependent. Furthermore, since the wireless channel of RFID systems is a two-way pinhole channel, the design of the tag plays a key-role in capturing the usable bandwidth in THz bands. This paper studies RFID based localization at THz band in indoor environments. We analyze the impact of distance and tag design on the RFID link budget. We also characterize the tag and distance dependent spectral windows that are feasible for RFID based localization. The localization requirements for RFID based localization are also presented in order to achieve high accuracy localization.","PeriodicalId":267901,"journal":{"name":"2018 First International Workshop on Mobile Terahertz Systems (IWMTS)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123346444","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}

First, we review how an ErAs monolayer in between p-i-n diodes enables serial connection of these diodes, reducing the total capacitance and thus decoupling the existing trade-off between RC- and transit time roll-off. In the second part of the paper, latest results with ErAs:In(Al)GaAs photoconductive devices are shown. Continous-wave (CW) receivers show an almost flat frequency response up to 0.5 THz with a noise equivalent power (NEP) of 20±10 fW/Hz. Under pulsed operation, we achieved 40 dB dynamic range at 4.1 THz with a system only using ErAs:In(Al)GaAs photoconductors as source and receiver.","PeriodicalId":267901,"journal":{"name":"2018 First International Workshop on Mobile Terahertz Systems (IWMTS)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124854084","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 the last few years a new interest was devoted to the longer wavelengths, in the so called “THz region” of the spectrum, due to the peculiar characteristics of the radiation in this spectral range, that make it ideal for applications in this field [1]: it's low photon energy and its ability to penetrate dielectric materials. This high penetration capabilities were used to demonstrate the possibility to detect artwork hidden under layers of other dielectric materials [2]–[4]. Making use of phase-sensitive techniques it is also possible to get information on the optical properties of the materials under study and to obtain images that include spectroscopic information about the sample [5]. Moreover, radiation in the THz range is strongly reflected and absorbed by water, and this feature can be used to study degradation in mural paintings and mosaics.","PeriodicalId":267901,"journal":{"name":"2018 First International Workshop on Mobile Terahertz Systems (IWMTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115605321","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}

Massive MIMO systems operating in the mmWave spectrum have many advantages in terms of e.g. beamforming and channel capacity, not only for communication systems but also for radar systems. Therefore, an experimental real time massive MIMO testbed utilizing sub-6GHz and the mmWave spectrum is to be constructed at Institute of Digital Signal Processing (DSV), University of Duisburg-Essen, Germany to investigate this technology in a practical manner for indoor radar system applications. The proposed testbed will initially be implemented for sub-6GHz frequencies with more than hundred antennas and later extended to the mmWave region. Obviously, the testbed design is very complex and a detailed design study is required before implementation. This paper summarizes findings of the design study. Firstly, a theoretical model of a signal processing architecture for a massive MIMO testbed is presented. This is followed by requirements and comparison of parameters processing power, bandwidth, data throughput etc. for sub-6GHz and mmWave spectrum. Also, mapping of algorithms on heterogeneous computational resources, such as FPGA, GPU and CPU is discussed. Based on the study, parameters for the proposed testbed are selected.","PeriodicalId":267901,"journal":{"name":"2018 First International Workshop on Mobile Terahertz Systems (IWMTS)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124033744","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}
