Synthesizing Shaped Power Patterns for Linear and Planar Antenna Arrays Including Mutual Coupling by Refined Joint Rotation/Phase Optimization

open access: yesIEEE Transactions on Antennas and Propagation, 2020
In this article, a novel strategy based on refined joint element rotation/phase optimization is presented to obtain vectorial shaped power patterns for antenna arrays with arbitrary element structures including mutual coupling. The active element pattern

A two-phase optimization model for the demand-responsive customized bus network design

open access: yes, 2020
This paper proposes a new optimization model for the network design problem of the demand-responsive customized bus (CB). The proposed model consists of two phases: inserting passenger requests dynamically in an interactive manner (dynamic phase) and ...
