Novel radiation signal detecting and non-contact probe modeling by Biot-Savart Theorem

In this paper, the key point is non-contacting measurement. Recent contacting probe has plenty of disadvantages such as low mobility, high cost, high damage rate, etc. In contrast, A non-contacting probe has the advantage of high-mobility, low-cost, well directivity, well reproducibility and broadband to receive or transmit signals between chips or ICs in 3DIC application, and using the Biot-Savart Theorem to establish physical model up to 16GHz and thus restore the signal radiation. Deriving from the electromagnetic theorem, the scattering parameter is then discovered. However, a completely reduction theory to compensate the coupled signal measured by non-contacting probe is needed. Compared with the model, the result of the restore theory has a high degree of similarity, and the result of the derived theorem is similar to actual measurement which can detect the signals in chips.
