WebThe layer closest to the earth is called the D-Layer. It does not reflect signals generally, but does absorb some of the energy, and hence the D-Layer is often called the "absorption layer." Higher up in our ionosphere, we find the E- and F-Layers. These layers do reflect the signals back to earth if they are below the MUF, and is exactly what ... WebThe ionosphere is composed principally by free electrons. When this two regions are in contact, it makes a new region called the D layer. This layer is responsible of the high attenuation in LF and HF transmission, below 6 Mhz. imprimante hp 6220 carrefour
