We consider a two-stage stochastic optimization problem, in which a long-term optimization variable is coupled with a set of short-term optimization variables in both objective and constraint functions. Despite that two-stage stochastic optimization plays a critical role in various engineering and scientific applications, there still lack efficient algorithms, especially when the long-term and sho...Show More
The high-order modes of the periodic-stub-loaded stripline are studied by using an equivalent circuit, which shows a good accuracy and efficiency. Due to the similarity, the proposed structure is compared with the spoof surface plasmon transmission line developed in recent years, and it reveals advantages for electromagnetic compatibility. Two approaches are introduced to suppress different transm...Show More
In this paper, an electromagnetic probe is proposed for the near-field scanning. Its detection section is made of a miniature loop-wire hybrid structure, which can measure Hx, Hy, and Ez simultaneously. It is optimized to achieve a wide working band from 0.1 to 15 GHz. The calibration and measurement error of the probe are discussed in detail. The probe is fabricated as a four-layer printed circui...Show More
In this paper, a wideband and high sensitivity magnetic probe is designed for the near-field scanning. To achieve the high sensitivity, the size of the probe aperture is fixed as 1 mm by 1 mm. On the basis of the fixed size, reducing the length of the loop wire and optimizing the width of the loop wire are adopted to reduce the parasitic inductance and capacitance, in order to increase the highest...Show More
A new equivalent dipole model hybrid with artificial neural network (ANN) is proposed in this paper for electromagnetic interference (EMI) estimation. Equivalent dipole method, based on the free-space Green's function, is usually used to model unknown EMI sources on printed circuit boards. For high-speed and dense circuits, there may be multi-reflection and/or diffraction between the EMI source an...Show More
The near-field scanning is an effective technology for electromagnetic interference (EMI) diagnosis. An accurate and efficient near-field-to-near-field transformation in the reactive near-field region of the EMI radiation source plays an important role in the near-field scanning. In this paper, an efficient near-field-to-near-field transformation based on the electromagnetic probe calibration is p...Show More
In this paper, a simple and accurate equivalent circuit of the magnetic probe is proposed. Based on the equivalent circuit, a high-frequency probe for near-field measurements is proposed, manufactured, and tested. To increase its working frequency, its parasitic inductance and capacitance are reduced by using a small loop aperture and a tapered transition. The working frequency of the probe is up ...Show More
Electromagnetic interference (EMI) source reconstruction typically requires accurate measurements of both near-field magnitude and phase information. In some cases, an accurate phase measurement may not be practically feasible. A phase-retrieval method based on phaseless and single-plane near-field scanning is presented in this paper. By using an interpolation technique, the original data of field...Show More
