To this end, we characterized the dielectric properties of animal liver, muscle, fat and blood in the microwave frequency range from 0.5 GHz to 7 GHz and in the temperature range between 30 \u00b0C and 50 \u00b0C. The measured data were modeled to a two-pole Cole-Cole model and a second-order polynomial was introduced to fit the Cole-Cole parameters as a function of temperature. The parametric model provides access to the dielectric properties of tissue at any frequency and temperature in the specified range.<\/jats:p>","DOI":"10.3390\/s19071707","type":"journal-article","created":{"date-parts":[[2019,4,10]],"date-time":"2019-04-10T11:25:08Z","timestamp":1554895508000},"page":"1707","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":61,"title":["Ultra-Wideband Temperature Dependent Dielectric Spectroscopy of Porcine Tissue and Blood in the Microwave Frequency Range"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5202-3082","authenticated-orcid":false,"given":"Sebastian","family":"Ley","sequence":"first","affiliation":[{"name":"Biosignal Processing Group, Technische Universit\u00e4t Ilmenau, 98693 Ilmenau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Susanne","family":"Schilling","sequence":"additional","affiliation":[{"name":"Biosignal Processing Group, Technische Universit\u00e4t Ilmenau, 98693 Ilmenau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8259-0611","authenticated-orcid":false,"given":"Ondrej","family":"Fiser","sequence":"additional","affiliation":[{"name":"Department of Biomedical Technology, Faculty of Biomedical Engineering, CTU in Prague, 272 01 Kladno, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan","family":"Vrba","sequence":"additional","affiliation":[{"name":"Department of Electromagnetic Field, Faculty of Electrical Engineering, CTU in Prague, 160 00 Prague, Czech Republic"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00fcrgen","family":"Sachs","sequence":"additional","affiliation":[{"name":"Electronic Measurements and Signal Processing Group, Technische Universit\u00e4t Ilmenau, 98693 Ilmenau, Germany"},{"name":"ILMSENS GmbH, 98693 Ilmenau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6167-9748","authenticated-orcid":false,"given":"Marko","family":"Helbig","sequence":"additional","affiliation":[{"name":"Biosignal Processing Group, Technische Universit\u00e4t Ilmenau, 98693 Ilmenau, Germany"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2119","DOI":"10.1109\/TMTT.2013.2255884","article-title":"Microwave breast imaging with a monostatic radar-based system: A study of application to patients","volume":"61","author":"Fear","year":"2013","journal-title":"IEEE Trans.
