An Approximate Analytical Method for a Slot Ring Radome Article

In this paper, an in-band and out-of-band microwave wireless power-transmission characteristic analysis of a slot ring radome based on an approximate analytical method is proposed. The main contribution of this paper is that, in the approximate analysis of the ring radome, a unified expression of the incident field on the radome surface is derived with E-plane and H-plane scanning, and the ring is approximated as 30 segments of straight strips. Solving the corresponding 60 × 60 linear equations yields the electric current distribution along the ring strip. The magnetic current along the complementary slot ring is obtained by duality. Thanks to the fully analytical format of the current distribution, the microwave wireless power-transmission characteristics are efficiently calculated using Munk's scheme. An example of a slot ring biplanar symmetric hybrid radome is used to verify the accuracy and efficiency of the proposed scheme. The central processing unit (CPU) time is about 690 s using Ansys HFSS software versus 2.82 s for the proposed method.

Research on the equivalent circuit parameter of single linear induction motor

Strategic Study of CAE 2008, Volume 10, Issue 8, Pages 76-80
The SLIM parameter has clear error to its real value on the base of the RIM parameter measurement method because it has larger air gap and edge effect. This paper proposes a new scheme suited for SLIM parameter detection. It only needs input total power, phase voltage, phase current, frequency, and then computes primary resistance, primary leakage induction, secondary resistance, secondary leakage induction, air induction and iron loss resistance. The performance analysis of SLIM indicates that this method is very effective and valuable.
