 The backscatter -the energy radiated directly back to the transmitter -increases as the wavelength goes up, or the frequency decreases  When design
{"Image DocumentName": "The backscatter -the energy radiated directly back to the transmitter -increases as the wavelength goes up, or the frequency decreases", "Image ImageDescription": "When designing a cavity for minimum return, it is important to balance the forward scatter associated with. ray tracing with the backscatter from interactions with the first surfaces. Although surface alignment is very important for external surfaces and inlet and exhaust edges, the return from the inside of a cavity is heavily dependent on attenuating materials.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
