We use an atomistic strain model that has a cubic geometry and includes nearest neighbor bonds, next nearest neighbor bonds, and bond bending terms. Our motivation is the well established fact that for many heteroepitaxial systems growth proceeds in the Stranski-Krastanov growth mode, where islands form after the

By inserting complementary radiation structure that is shorted (shorted radiation structure: srs), coupling between antennas in the commercial handset is dramatically decreased without the variation of return losses and efficiency.

The phones should have equipped two internal antennas and two SIMs (Subscriber Identity Modules) for dual-standby mode operation. In ...
