This paper deals with microwave absorption and ultrasonic techniques with different liquid polymers. Ultrasonic Testing (UT) could be a cluster of nondestructive examination (NDE) techniques that use short, high-frequency Ultrasonic waves to spot flaws in an exceedingly material. They typically work by emitting waves into a fabric. By measure, these waves, the properties of the fabric and internal flaws are known. Most UT devices include several separate units. These will embrace pulsars and receivers, transducers, and show monitors. The elements enclosed depend upon the kind of UT that the inspector is acting.

Keywords: Microwave, Ultrasonic, Testing.
