The coating is produced through the dispersion of either commercial graphene nanoplatelets (GNPs) or carbon nanofibers (CNFs) in 1-propanol and the deposition of the so-obtained colloidal suspension onto the RC surface with a bristle brush. Finally, a polymeric film is deposited over the carbon-based lossy layer in order to protect the lossy coating from the external environment. The electromagnetic properties of the produced panels are investigated through reflection coefficient measurements in the X and Ku bands. It is demonstrated that the RAM with the GNP-based lossy layer has a -10 dB bandwidth of ~7 GHz, but the polymeric top layer degrades its performances, resulting in a minimum reflection coefficient of -9 dB. With the CNF-based lossy layer it is possible to fabricate a RAM with a -10 dB bandwidth of ~10 GHz. The application of the protective layer reduces the bandwidth to ~6 GHz.","PeriodicalId":326016,"journal":{"name":"2016 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126772747","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}

For discharge points on the back side of the phone this leads to a situation in which the display is facing the HCP. The phone or tablet forms a capacitance between 50 pF and 300 pF to the HCP. The capacitance value depends on the size of the phone, its screen flatness, and the flatness of the insulator which may deteriorate over time. The discharges to the phone lead to a large displacement current flowing through the display. This current has multiple paths to the body of the phone: via the touch electronics, via the display electronics, and directly to the body of the phone. As these currents can reach 30 A (at 8 kV contact mode) they can lead to upset and damage of both the display and the touch layers. This paper provides analysis of the display down test situation in order to show reproducibility problems. The effect of the capacitance variation is shown by the measurement and the PSPICE model. Full-wave model was used to help understand how much of the total current flows through the body of the phone. The Lichtenberg dust figure method was used to show the contribution of the corona discharge.","PeriodicalId":326016,"journal":{"name":"2016 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126642075","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 study is performed on a second generation peripheral component interconnect express (PCIe Gen II) interface with 5.0 Gbps transfer rate. A set of full wave simulations are performed on a printed circuit board with the PCIe interface implemented in an embedded micro-strip line structure. Lossy material patches are applied onto the channel to reduce the electromagnetic radiations from differential pairs. This reduction might be required especially in compact mixed signal systems as noisy digital circuits are located close to radio-frequency receivers with stringent sensitivity limits. Using the numerical solver, it has been shown that the application of the absorber can reduce the magnitude of the received electromagnetic fields at the desired locations while unfortunately affecting the signal integrity performance of the bus. In order to reduce the unintentional discontinuity introduced along the differential pairs as applying the material on the PCB, the insertion of a dielectric spacer sheet between the absorber and the solder mask is investigated. It has been shown that the presence of a thin layer of the spacer (less than 0.2mm) can significantly decrease the introduced mismatch while still keeping the benefit of the EM reduction. Full wave simulation results are being confirmed by near field probing set-up and a PCIe compliance test board.","PeriodicalId":326016,"journal":{"name":"2016 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117164635","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 data rate increases and metal-to-metal space decreases to achieve higher system bandwidth, crosstalk effects degrade the signal integrity. Therefore, estimation and reduction of the crosstalk effects are essential on HBM interposer channel. In order to estimate crosstalk effects in short time with high accuracy, PDA-based estimation method is proposed. In addition to the proposed method, wide space and guard trace with ground vias structures are suggested and compared based on the estimated eye-diagrams. With the estimated eye-diagrams, voltage fluctuation on DC levels due to the crosstalk effects can be analyzed. Worst and statistical eye-diagrams of interposer channels including crosstalk effects are estimated. Since the proposed method needs only output and crosstalk response of the channel, the proposed method can be applied to multiple wide I/O channels.","PeriodicalId":326016,"journal":{"name":"2016 IEEE International Symposium on Electromagnetic Compatibility (EMC)","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130460291","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}
