نویسندگان
چکیده
A numerically effective description of the total active reflection coefficient and realized gain is studied for multiport antennas. Material losses are fully considered. The based on operators represented in an entire-domain port-mode basis, i.e., matrices with favorably small dimensions. Optimal performance investigated, conditions optimal excitation matching derived. solution to combinatorial problem ports' placement feeding synthesis also accomplished. Four examples various complexities studied, demonstrating advantages proposed method. final formulas can easily be implemented existing electromagnetic simulators using integral equation solver.

Total internal reflection and evanescent gain.
Total internal reflection occurs for large angles of incidence, when light is incident from a high-refractive-index medium onto a low-index medium. We consider the situation where the low-index medium is active. By invoking causality in its most fundamental form, we argue that evanescent gain may or may not appear, depending on the analytic and global properties of the permittivity function. Fo...
متن کاملImpedance and quality factor of mutually coupled multiport antennas
In this study, expressions for the radiation quality factor Q and the input impedance seen at any terminal of a multiport antenna are derived. It is shown computationally that because of the possibility to adjust the antenna current distribution through suitable feeding/loading a multiport antenna can perform lower Qs than a similar single-port antenna. © 2008 Wiley Periodicals, Inc.

متن کاملOptimal designs for dose finding studies with an active control
Dose finding studies often compare several doses of a new compound with a marketed standard treatment as an active control. In the past, however, research has focused mostly on experimental designs for placebo-controlled dose finding studies. To the best of our knowledge, optimal designs for dose finding studies with an active control have not been considered so far. As the statistical analysis...

uncertainty in the financial market will be driven by underlying brownian motions, while the assets are assumed to be general stochastic processes adapted to the filtration of the brownian motions. the goal of this study is to calculate the accumulated wealth in order to optimize the expected terminal value using a suitable utility function. this thesis introduced the lim-wong’s benchmark fun...
15 صفحه اولUtilizing Generalized Learning Automata for Finding Optimal Policies in MMDPs
Multi agent Markov decision processes (MMDPs), as the generalization of Markov decision processes to the multi agent case, have long been used for modeling multi agent system and are used as a suitable framework for Multi agent Reinforcement Learning. In this paper, a generalized learning automata based algorithm for finding optimal policies in MMDP is proposed. In the proposed algorithm, MMDP ...
