Impact of Coil Area:
It analyzes the trade-off between coil area and PTE, exploring how geometry affects efficiency.
Tissue Interaction:
The study incorporates the effects of tissue as a medium on power transfer and adjusts coil parameters accordingly.
Practical Implementation:
A prototype operating at 20 MHz is simulated using tools like Ansys HFSS, demonstrating the proposed design’s effectiveness in a tissue environment.
The goal is to replicate this assignment on python. Here is how….
Replicating the Study in Python:
Here’s a high-level roadmap to replicate the analysis using Python:
The five problem
1. Define Coil Parameters and Formulas:
Use the equations for self-inductance, optimal frequency (fopt), and coupling coefficient (k).
Example: Calculate Lopt using the provided formula.
2. Optimize the Inductive Link:
Implement functions for S-parameters (|S21|, etc.) to evaluate PTE.
Example: Use the formula for |S21| and optimize it to find fopt.
3. Incorporate IMNs:
Model and simulate L-section impedance matching networks using transmission line theory.
Example: Implement matrix calculations for IMN as described.
4. Simulate the Environment:
Simulate the effects of tissue (e.g., resistance and inductance changes) using provided formulas.
5. Visualization and Validation:
Use Python libraries like Matplotlib for plotting PTE vs. frequency or coil area.
Compare results to theoretical expectations or available simulation benchmarks.
