“…As THz wave suffers negligible loss through the dry air, a variety of structures with air-core become another possible option to design low-loss THz waveguide, such as pipe waveguide [10], hollow Bragg fiber [11], porous core fiber [12][13][14], porous core photonic crystal fiber [15,16] and hollow-core waveguide [17][18][19]. In these waveguides, a significant portion of the modal power is guided through the low-loss air.…”

This is the accepted version of the paper.This version of the publication may differ from the final published version. Abstract-Designs of hollow-core rectangular, circular, and elliptical waveguides with inner coating of silver and polystyrene (PS) are presented for low-loss terahertz guidance. The PS thickness deposited over silver is optimized to achieve the lowest possible loss for each waveguide at the frequency of 2.5 THz. The mode also tends to be a near-Gaussian in shape, easy for coupling to transmitter and receiver. The lowest propagation loss of 0.13 dB/m is obtained for the 02 LP mode in a circular waveguide with 2200 µm bore diameter by using a full-vectorial finite element method. It is also shown here that rectangular and elliptical waveguides with a similar core area offer a lower loss value for the Permanent repository link

“…But still these proposed waveguides had to challenge to satisfy flexible, efficient, lowloss transmission of broadband THz waves for long-length delivery. In order to achieve lower the propagation loss, a large part of transmitted radiation should be confined in air while propagating small portions into the material [17,18] as dry air has lower absorption loss and dispersion than any other material in the THz band [10,19]. In recent years researchers have reported porous core photonic crystal fibers (PCFs) as an improved option for THz wave transmission.…”
