Elevated blood pressure is a major risk factor for heart disease that affects millions of people across the world. Non-invasive blood pressure monitoring techniques have been limited to extremities of the body, like limbs, and are unable to measure dynamic internal pressures observed in deeper internal anatomical spaces like cardiac chambers, principal veins, cranial cavity, etc. Novel methods to investigate the internal biological pressures non-invasively can unlock new therapies to treat a wide range of diseases. Microwave-based sensing for biomedical applications is an active research area with the potential to expand in sensing vital physiological indicators like pressure. This study is an experimental investigation into the role of pressure on the dielectric properties of water to broaden the biomedical applications of microwave-based sensing. An experimental setup consisting of a pressure chamber with water and a co-axial probe was built to measure the dielectric properties at pressures ranging from 0 to 240 mm of Hg over a frequency range of 0.5-20 GHz. A comparison of the measurements shows a small and significant change in dielectric properties with varying pressures revealing the challenges and a direction for future scientific research.","PeriodicalId":383636,"journal":{"name":"2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124779189","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}

Due to their nature, absorbers have different reflection coefficient values depending on the incidence angle and frequency of operation, albeit the reflection coefficient values depending on the angles are seldom shown on the specification sheets of commercially available absorbers. In this study, a chamber illuminated with a semi-isotropic antenna is simulated to calculate the incidence angles of the EM waves on the absorbers. The obtained results are presented as a percentage distribution of incidence angles. It is seen that, most of the reflections occur at angles far from normal incidence. Quiet zone analyses with and without angle dependent reflection coefficient values are carried out to quantify the error made by assuming a constant reflection coefficient. It has been quantitatively shown by three examples that a better isolation level estimation can be made if the angle dependent reflection coefficient values are taken into account.","PeriodicalId":383636,"journal":{"name":"2023 IEEE International Symposium on Antennas and Propagation and USNC-URSI Radio Science Meeting (USNC-URSI)","volume":"76 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114920580","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}
