| Structural deformation due to magnetic forces
EMS couples between the magnetic and structural analyses. In this example, a magnetic system made of two current-driven concentric coils and a test body surrounded by a highly saturable ferromagnetic yoke, i.e. Silicon Steel RM50, as shown in Figure 1. EMS first computes the internal force density in the ferromagnetic material and then feeds it into the built-in structural module which, in turn, computes the deformation and stress in the magnetic system. Both the magnetic and structural modules use the same mesh. Figure 2 shows the resulting displacement in the test body.

A New Discovery About Human Skin Could Help Us Eliminate Scarring
Scars are a normal part of life — for now, anyway. In the future, that might not be the case, as researchers have developed a method to eliminate scarring by prompting wounds to heal as normal skin rather than as scar tissue.

PIFA Antenna
HFWorks supports both S-parameters and Antenna analyses. It computes fields, antenna and circuit parameters. In this example, HFWorks is used to simulate a PIFA antenna, as shown in Figure 3. This type of antenna is mostly used for GPS and WiMAX applications. The parameterization feature of HFWorks is used to study the effect of the L3 dimension on the circuit and antenna parameters. Figure 4 shows the return loss, i.e. S11, as a function of L3. Figure 5 shows the 3D gain pattern at the first resonant frequency i.e. 3.363 GHz.
