DEKA microwaves are not just smart.  They are cool!

Onda is the only system using patented Coolwaves™, special microwaves that selectively target fat cells to reduce localized fat deposits in a safe, effective and non-invasive way.

The Onda system handpieces generate microwaves at 2.45GHz, a frequency that is preferentially absorbed by fat molecules rather than by water molecules. The conductivity of the epidermis and the dermis, which contain plenty of water but not fat, is therefore much greater than the hypodermis’ one. Therefore, when the Coolwaves™ penetrate the skin, they pass straight through the top layers without overheating them (using about 20% of the energy from the microwaves), while they concentrate their effective action on the subcutaneous fat that highly absorbs them (about 80% of the energy). By contrast, traditional radio frequency systems (frequency range 0.1 - 40MHz) act only on the surface since highly absorbed by water molecules. This means that they not only fail to penetrate deep into the body to treat fat, but they also risk to damage the skin.
