Main interference sources for electro-magnetic sensitive system in submarine platform are usually LF (low-frequency) electromagnetic radiator like high-power cable or cabinet in cabin. The characteristic and problem of radiated EME (electromagnetic environment) from cable and cabinet was analyzed, and a hybrid simulation method of EME from cable based on MoM (method of moments) and MTL (methods of...
The low-frequency electromagnetic radiation of cabinet has became the main interference source for electromagnetic sensitive system. The feature of interference sources in cabinet was analyzed, and the electric dipole is considered as the equivalent interference source. Then, considering the low-frequency radiation characteristic, the low-frequency MoM is used to simulate the electromagnetic environment...
As a novel simulator used for EMC testing, broadband gigahertz field simulator (BGF) was invented by podgorski et al. for simultaneous testing in dual polarization of emission and susceptibility. However, the dimensions and mechanism of BGF are still undisclosed in details. According to podgorski's designing, we had designed the BGF model for vertical polarization emission and susceptibility testing...
The model of the shipboard cabin was developed and the electromagnetic environment (EME) in it was simulated by using the electromagnetic field analysis software FEKO. The EME in the shipboard cabin varying with the number of antennas on deck, the distance between the antenna and cabin, and the transmitting power of antennas was obtained, and their dependent relations were also presented. The results...
A Magnesium Doped Layer (MDL) under the 2-DEG channel and a Drain Metal Extension (DME) are proposed to provide a new degree of freedom in the optimization between breakdown voltage (BV) and specific-on-resistance (Ron-sp) in AlGaN/GaN HEMTs. The surface electric field of the proposed structure is distributed more evenly when compare to the MDL-only structure with the same dimensions. A breakdown...
It has been over 10 years since the military standards GJB151A/152A were published in 1997. Thus their applicability is worth studying, such as the item of RS103 used for surface ship. The model of the shipboard cabin was developed and the electromagnetic environment (EME) in it was simulated by using the electromagnetic field analysis software FEKO. The EME in the shipboard cabin varying with the...
