Technology Highlights

• The invention provides precision in axial symmetry of the plasma excitation.
• The invention allows for either magnetic or electric excitation of the plasma. This provides flexibility in how the plasma is excited and controlled.
• The invention's adapter can be used with the current systems without needing a complete redesign, making it easier to integrate into existing setups.
• The invention used or optimized for different plasma dimensions, shapes and densities. The adapter's ability to shape the electromagnetic field means that the heating can be precisely controlled.
• The invention provides the shaping of the electromagnetic field ensures that the energy is more evenly distributed across the plasma.
• The invention improves the heating efficiency by using an adapter to tailor the electromagnetic field to better couple with the plasma hence, more energy from the microwave frequencies can be transferred into the plasma.
• The invention provides less wasted energy, making the entire process more resource-efficient.
