Struktur berbentuk gegelung dicadangkan untuk meningkatkan sensitiviti dan resolusi spatial untuk siasatan medan dekat EMI. Reka bentuk ini menghasilkan sensitiviti yang tinggi dan resolusi spatial yang baik untuk mencari sumber EMI di kawasan berhampiran medan. Kedua-dua ciri adalah penting untuk mendiagnosis pelepasan daripada peranti elektrik dan elektronik. Reka bentuk baharu ini menghasilkan sensitiviti yang unggul, yang secara amnya 15 dB lebih besar daripada probe konvensional. Siasatan baharu ini membantu pengamal mencari kawasan sumber pelepasan hingar dengan cepat dan betul pada papan litar bercetak dan peranti. Dua prototaip berbeza saiz telah dibuat. Yang lebih besar memberikan sensitiviti yang tinggi manakala yang lebih kecil boleh menentukan lokasi sumber pelepasan. Reka bentuk probe baharu juga mempunyai ciri invarian orientasi. Tahap tindak balas hingarnya adalah serupa untuk semua arah probe. Ciri ini boleh membantu mengurangkan kebarangkalian pada kesilapan pengesanan kerana sensitiviti sebahagian besarnya tidak berubah kepada orientasinya. Pengukuran yang meluas telah dilakukan untuk mengesahkan mekanisme operasi dan untuk menilai ciri siasatan. Ia sesuai dengan diagnosis masalah gangguan elektromagnet.

Abstract: Coil-shaped structures are proposed to enhance sensitivity and spatial resolution for EMI near-field probe. This design yields a high sensitivity and a good spatial resolution to find the EMI source in near-field region. Both characteristics are crucial to diagnosis of emissions from electrical and electronic devices. The new design yields a superior sensitivity, which is in general 15 dB greater than conventional probes. This new probe helps practitioners to quickly and correctly locate noise emission source areas on printed circuit boards and devices. Two prototypes of different sizes were fabricated. The larger one provides a high sensitivity while the smaller one can pinpoint emission source locations. The new probe design also has an orientation invariance feature. Its noise response levels are similar for all probe directions. This characteristic can help reduced the probability at miss-detection since sensitivity is largely invariant to its orientation. Extensive measurements were performed to verify the operation mechanism and to assess probe characteristics. It suits well to the electromagnetic interference problem diagnosis.
