Os campos eletromagnéticos emitidos por um evento de descarga eletrostática (ESD) que ocorre entre metais carregados causam sérios danos a equipamentos de alta tecnologia. A fim de esclarecer o mecanismo de geração de tais campos ESD e também para reduzi-los, propusemos anteriormente um algoritmo de diferença finita no domínio do tempo (FDTD) baseado em um método de alimentação delta-gap e uma fórmula característica de dispersão de frequência (fórmula de Naito) de material de ferrite para simular os campos ESD devido a uma faísca entre os metais carregados com fixação de núcleo de ferrite. No presente estudo, integrando o algoritmo FDTD acima e uma fórmula de resistência à faísca, simulamos tanto o próprio ESD quanto os campos resultantes para as barras de metal com fixação do núcleo de ferrite e demonstramos que a fixação do núcleo próximo ao centelhador suprime o nível do campo magnético. Esta descoberta também foi validada por meio de medição de banda larga de 6 GHz do campo magnético próximo.

Abstract: The electromagnetic fields emitted from an electrostatic discharge (ESD) event occurring between charged metals cause seriously damage high-tech equipment. In order to clarify the generation mechanism of such ESD fields and also to reduce them, we previously proposed a finite-difference time-domain (FDTD) algorithm based on a delta-gap feeding method and a frequency dispersion characteristic formula (Naito's formula) of ferrite material for simulating the ESD fields due to a spark between the charged metals with ferrite core attachment. In the present study, by integrating the above FDTD algorithm and a spark-resistance formula, we simulated both of the ESD itself and the resultant fields for the metal bars with ferrite core attachment, and demonstrated that the core attachment close to the spark gap suppresses the magnetic field level. This finding was also validated via 6-GHz wide-band measurement of the magnetic near-field.
