The shielded-loop coil and via fences are used in the probes to provide better electric field coupling suppression. Type I probe is designed to receive horizontal magnetic field, via fences are inserted in the loop aperture and along sides of the probe to reduce electric field coupling from sides. The inner size of the loop aperture is 700×380 μm. The flip-chip bonding, which has low insertion loss and the good shielding capability, is also used in this probe. We take this probe over a 2000-μm-wide microstrip line as device under test (DUT) in measurements, the isolation between electric and magnetic field is better than 10 dB up to 11.5 GHz. The spatial resolution of the probe is 300 μm at 11 GHz. Type II probe is designed to receive the vertical magnetic field. The detected signal is passed along a right-angle channel surrounded by cylindrical via fences. Via fences are also set around the loop and give good shielding to reduce the electric field interference. The inner diameter of the loop aperture is 670 μm. For this vertical magnetic field probe, the measured minimum isolation between electric and magnetic field is 15.17 dB at 17.35 GH up to 20 GHz.

Kichouliya, D. Devender, V. Ramasarma, D. Reddy, V. G. Borkar","doi":"10.1109/ISEMC.2011.6038445","DOIUrl":"https://doi.org/10.1109/ISEMC.2011.6038445","url":null,"abstract":"HERO is one of the critical electromagnetic environmental effects as defined in the MIL-STD-464A. The HERO electromagnetic environment is very severe for the ship born systems, as it contains the sources of Electromagnetic environments (Radars, HF Transmitters and VHF communication systems etc.) and ordnance systems on the same platforms. Necessarily most of the ordnance system contains the EEDs/EIDs, and these are fired as and when the operation of the ordnance system is desired. HERO environment has the potential threat to cause an inadvertent actuation or firing of these ordnance systems by inducing the sufficient current in the EEDs/EIDs circuits. This results into a disaster and causing the loss of ordnance system along with collateral effects, platform, cost and human being. So now it has become essential to certify every ordnance system to be HERO safe and reliable, when it is on board or when it moving in the stock-pile to safe operation. The HERO environment defined in MIL-STD-464A calls for generation of very high field strength (i.e. 2620 V/m @ 2.7-3.6 GHz), which is really a challenge to generate inside the laboratory. So to overcome this practical difficulty the MIL HDBK-240 suggested to use extrapolation method for high fields, provided the bridge wire should exhibit the linear characteristics. The aim of this paper is to demonstrate the extrapolation method (MIL-HDBK-240) for assessing the induced current on the bridge wires at very high fields. The induced current measurement system on bridge-wire consists of Fibre-optic temperature (FOT-HERO) sensor and the signal conditioner, which works on the principle of Fabry-Perot Interferometery (FPI). To verify the extrapolation FOT-HERO sensor mounted bridge-wire will be exposed to the different electromagnetic field levels at specified spot HERO test frequencies. The measured induced currents at the lower field levels will be extrapolated to higher field level to compute the induced currents at high field levels, and then it will be compared to the actual measured results and finally with the safety margin (i.e. 15% of the Maximum No Fire Current (MNFC)) of the ordnance system.","PeriodicalId":440959,"journal":{"name":"2011 IEEE International Symposium on Electromagnetic Compatibility","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124038056","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}
