In this letter, a novel and original configurations of highly efficient [Formula Omitted] and [Formula Omitted] beam splitters based on a photonic crystal with wide operating frequency band over the wavelength range, respectively (1.519-1.569) [Formula Omitted] and (1.544-1.564) [Formula Omitted] for terahertz communication applications are proposed. This is the most important results found in terms of transmission ever seen from these two devices in comparison with the literature. It is found that the efficient total transmissions of [Formula Omitted]% and 96% for the [Formula Omitted] and [Formula Omitted] splitters, respectively, with very low insertion losses at output ports are obtained around the wavelength of [Formula Omitted]. The simulation results confirm that the current designs can provide an efficient splitting over a broad bandwidth of [Formula Omitted] nm for [Formula Omitted] splitter and 20 nm for the [Formula Omitted] splitter, respectively.
