Abstract
Two types of Kagome PCFs such as the slotted core PCF and circular PCF have been proposed. Finite element method is employed with boundary conditions to analyze the optical properties of the suggested PCFs. HRS and Epsilon Near Zero materials are employed in core and TOPAS as the background material. A wide frequency ranges for 0.8 THz to 2 THz is applied with numerical analysis. Novelty of the paper, we have proposed two Kagome PCFs with different core formations. One PCF is elliptical and rectangular hole based slotted core Kagome PCF, and another one is a circular hole in hexagonal formation based core Kagome PCF. We have investigated the optical properties by tuning the geometry of the PCFs. The main advantages of the proposed PCF are that it shows better results in terms of Dispersion, Birefringence, confinement loss, bending loss, effective material loss, total loss and V-parameters. The results have also been compared with previous papers. Furthermore, the structural design has been described, and numerical results have also been described in this paper. The structure is not complex and can be fabricated by employing well-known fabrication techniques.
