title: Measuring the reflection of electromagnetic waves from foam structures of varied foaming ratio
abstract: A specific multi-frequency technique for measuring the reflectivity of constantly collapsing foam structures of varied initial foam ratio is developed. A measuring and computing complex implemented the technique is used. It operates in the microwave range from 38 to 52 GHz. Dynamic foam structures with an initial foaming ratio of 55, 108, and 156 units in the form of flat-layered foam samples with a fixed thickness are under measurement. It is shown that the use of foam structure covering allows
