Phase Field Failure Modeling: Brittle‐Ductile Dual‐Phase Microstructures under Compressive Loading
Advanced Engineering Materials, EarlyView.The approach by Amor and the approach by Miehe and Zhang for asymmetric damage behavior in the phase field method for fracture are compared regarding their fitness for microcrack‐based failure modeling. The comparison is performed for the case of a dual‐phase microstructure with a brittle and a ductile constituent.

Reduction of mutual coupling between closely spaced PIFAs
Electronics Letters, 2010 A new approach for reducing mutual coupling between planar inverted-F antennas (PIFAs) is proposed. The approach consists of placing a resonator in between the PIFAs. The signal from the first antenna is scattered by the resonator and couples to the second antenna creating another path for mutual coupling, the phase and amplitude of which may be varied
