| SAM head model with cell phone |
| |
| The SAM head model with a cell phone nearby is simulated by using GEMS. The MIMO antenna includes two ports and the outputs will be S-parameters, far field patterns, ECC and MEG, and 1-g SAR, 10-g SAR, peak SAR and 3-D SAR distribution. |
| |
| The basic design procedure in the simulation: |
 | Import the SAM head model in the SAT format and specify the material type for both the plastic shell and inner human tissue equivalent material | | Import the cell phone model in the SAT format and specify the material type for each part | | Add two ports and assign them two different source group IDs, say, 1 and 2 | | Specify the far field pattern parameters | | Select the human head model, copy and paste it, and specify the SAR output | | Generate the adaptive mesh | | Specify the convergence criterion | | Simulate the project using a single PC or cluster |
|
| The basic settings in the simulation: |
| Option | Setting | Description | | Boundary | PML truncates all six walls | Open space problem | | Excitation | Lumped port | With different IDs | | Mesh | Non-uniform and conformal mesh | Adaptive mesh | | Output | S-parameters, far field pattern, and SAR | You can output the SAR near the cell phone | | Simulation | A PC or cluster | |
