    This paper proposes how to analyze and design the Line Impedance Stabilization Network (LISN). The details are described component characteristics and how to design air coil inductors in single and multi layers based on a high self resonant frequency response concept. According to the CISPR 16-1 standard, the stabilized impedance 50 Ω of LISN at frequency range 150 kHz to 30 MHz is proved by simulation and experimental results. The proposed LISN is successful design the low cost by compare with commercial LISN. Finally, the performance of the proposed LISN is achieved comparing to CISPR standard and also with commercial LISN. © 2007 IEEE.

    In this paper, the effect of an electric field on the growth of rice plants is studied. The research is focused on an electric field. The comparison is done under the conditions with electric field at 28.5 kV/m and without electric field. The rice plants are experimented with under the condition of the electric field. Rice is laid transversely and horizontally, respectively. The results with the electric field are compared to those without electric field. It is found that the rice plant growth with electric field has a high growth rate of the height of stems and the length of roots more so than in the case without the electric field.

    The improved electromagnetic interference (EMI) for single-stage single-switch AC/DC Power Factor Correction (S<sup>4</sup>PFC) by ripple-steering technique is presented. The suitable coupled inductor design, which used for steering the ripple that applied for single-stage single-switch AC/DC power factor correction, is fulfilled to gain a significantly conducted EMI reduction. The performance of modified boost inductor is shown by the implemented and discussed. Finally, the comparison between "modified boost inductor" and conventional "LC" filter in the EMI point of view is verified and experimented.
