In this paper, we present a multi‐band terahertz metamaterial composed of two hexagonal shaped metallic resonators supported by a Teflon dielectric substrate. The performance characteristics of the proposed structure are evaluated numerically using CST Microwave Studio software. The design has polarization sensitive and angle independent operational nature. The designed structure resonates at five...
Recent advancement in bioengineering and terahertz (THz) technology has stimulated interest in studying the interaction between THz radiation and biological agents, molecules and tissues. The THz imaging and testing system in clinical settings usually needs a samples holder to hold the freshly excised ex-vivo maligned specimen for diagnosis purposes. The conventional specimen holder being used in...
A terahertz (THz) beam splitter with forward and backward radiation beams is demonstrated. Unlike the conventional wire-grid polarizers, the proposed splitter can controlled the beam directions in two sides independently. The element of the splitter is composed of 4 metallic layers, which is supported by two substrate layers and separated by an air gap. In each element, two strips with backed wire-grid...
