As medical staff and visitors carrying wireless transmitters move through the hospital, there may be times when number and type of transmitters near a medical device produce an electric field that exceeds the equipment's immunity level. This paper presents a method for estimating the risk that the immunity level will be exceeded from wireless transmitters carried by medical staff throughout a 24-hour period. The method is applied to a simplified scenario of three patients in beds and twelve transmitter locations surrounding the beds, with eight medical staff on the floor. The risk of electromagnetic interference can be reduced with a suitable management policy. This paper describes a method for evaluating the usefulness of a management policy quantitatively, and then compares three policies: unrestricted use of wireless devices, restricted use, and a ban on wireless devices.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122711338","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}

A multi-layer MIC technology is adopted to reduce the circuit size of the oscillator. The oscillator consists of Gunn diodes, slot line resonators and microstrip lines. The Gunn diodes are embedded in the slot line resonators. The output circuit is formed using the microstrip line. A second harmonic signal can be obtained from the output circuit. A square-shaped slot line resonator is used in order to achieve the low phase noise and the suppression of undesired harmonics. The second harmonic oscillator is designed and fabricated in K band. The output power is +8.89 dBm at the design frequency of 18.75 GHz (2f0) with the phase noise of −116.2 dBc/Hz at the offset frequency of 1MHz. Excellent suppression of the undesired fundamental frequency signal (f0) of −33dBc is achieved. Moreover, the circuit size is reduced by three-tenths relative to that of the previous model of the proposed oscillator.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"27 10","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132287031","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}

A major class of passive electromagnetic field sensors are treated as antennas in the receiving mode and hence can be characterized using antennas time-domain parameters such as effective gain and fidelity. In this paper, these parameters have been calculated for a monopole antenna and an Asymptotic Conical Dipole (ACD). The antennas are modeled as wire structures. By solving a time-domain Electric Field Integral Equation (EFIE) using the method of moments (MoM), the induced current in the wires due to the incident electromagnetic field is determined. Knowing the induced time-domain current and the incident electric field, antenna effective height is calculated as a key parameter to evaluate time-domain characteristics of the sensors.","PeriodicalId":161657,"journal":{"name":"2010 14th International Symposium on Antenna Technology and Applied Electromagnetics & the American Electromagnetics Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123318194","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 fundamental guided mode of the designed waveguide has a quasi-TEM nature. This waveguide is designed to serve as a building block of a spatial power combiner and it is excited with an incident plane wave. A square lattice of metallic vias was added at the input and output faces of the EBG waveguide to prevent the incident plane wave from penetrating into the triangular lattice of holes and enhance the coupling between the guided mode inside the waveguide and plane wave excitation. The mode matching between the two different EBG waveguides with triangle and rectangle lattices has been investigated.
