Reflection range

WebA systematic study of the omnidirectional reflection range of one-dimensional photonic crystals with a staggered structure is presented, based on numerical simulations performed with the well-known transfer-matrix method without any simplifying assumptions. WebThe permissible frequency range in the case of sky wave propagation lies between 3 MHz to 30 MHz. Basically the electromagnetic waves in the range of 3 to 30 MHz get reflected by the ionosphere. However, the signals with frequency beyond 30 MHz despite undergoing reflection get penetrated.
