The propagation of H-polarized electromagnetic (EM) waves in polymeric (PEI)-chalcogenide (As2Se3) photonic materials (PCCPM) has been theoretically optimized and investigated in the current work. We used the Transfer Matrix Technique (TMT) and Hankel Realism (HR) in columnar coordinates to show numerical findings for the unit columnar junction and columnar slab for both polymeric (low refractive index) and chalcogenide (high refractive index) materials composed at least loss wavelength window (632.8 nm). The optical transmittance with wavelength for both materials for the cylindrical unitary slab displays oscillating and non-oscillating signatures, indicating that the starting radius has a significant impact on the transmittance at a constant slab width. The oscillatory transmittance becomes squizzing when the starting radius is increased. Furthermore, for smaller modal numbers, optical transmittance is an oscillatory function of slab thickness, and for (m=4), it becomes minimum and flat. These scientific breakthroughs pave the door for a variety of photonic devices and sensor applications.

“…The high and low RI periodic arrangement based concentric circular layer in length is the essential foundation of HCBF structure, where EM-wave is transmitted through the empty core under no. of Bragg reflections through the periodic claddings [24] , [25] , [30] . Under Bragg conditions, the HCBF structure also shows a photonic bandgap (PBG).…”

“…A band of wavelengths known as the PBG range is not permitted to pass through the HCBF structure. HCBF has many encouraging applications in doubly tuned multi-wavelength LASER sources [26] , biosensors [27] , tunable voltage multiplexers [28] , wavelength and intensity modulation [29] , [30] , etc. In this paper, the high RI contrast (e.g., chalcogenide glass Arsenic tri-selenide

and polymer film Poly-ether imide PEI) and multi-clad HCBF structure has been investigated.…”
