Oval-Square Hole System
Ellipsoidal Baffle Systems
The ellipsoidal baffle system is a device that provides acoustic performance in reverberation spaces without the need for physically separate absorption and reflection panels. This article describes the features and features of an ellipsoidal baffle system and tries to ......
Plasma induction furnace
Plasma Induction Ovens
When the gas molecules in a material come into contact with the RF (radio frequency) field generated by a plasma induction oven, the gas molecules get excited and ionize, forming ions and electrons that move towards the RF field. This process, known as ionization, is what m......
