Bragg reflectors for cylindrical waves

Towards a highly efficient air purifier using annular photonic crystals in UV regimes

“…In order to analyze the optical characteristics of APCs, the electric and magnetic elds at the interfaces of APCs are studied using the transfer matrix method (TMM) in cylindrical coordinates. 30 For cylindrical Bragg wave, TE and TM are the two possible polarization modes. The non-zero electromagnetic elds TE mode, are E z , H f and H r .…”

“…APCs attracted attention since Kaliteevski et al untiles the transfer matrix method in the cylindrical coordinates to describe the eclectic and magnetic elds inside coaxial layers. 30 APCs found a lot of applications in laser emission, optical communication, and optical electronics. 22,31,32 Moreover, researchers found that APCs have better sensing capabilities than planar PCs, which are promising with many chemical and biological applications.…”

Biophotonic sensor design using a 1D defective annular photonic crystal for the detection of creatinine concentration in blood serum

“…[27][28][29][30] Basically, an early study by Kaliteevski et al attracted the attention of various research groups toward APCs aer they studied the propagation of electromagnetic waves inside APCs with the help of a modied transfer matrix method for cylindrical multilayer structures. 31 Many researchers have since carried out innovative work showing better sensing capabilities for APC structures in comparison to planar photonic structures. [32][33][34] Moreover highperformance APC-based sensor designs using different materials are easy to realize and have promising applications in the eld of laser emission, optical communication, and optoelectronics.…”

Towards Promising Platform by Using Annular Photonic Crystals to Simulate and Design Useful Mask

“…Such structures are known as annular photonic crystals (APCs), circular photonic crystals, or cylindrical Bragg reflectors [34,35]. APCs have attracted significant interest, since Kaliteevski et al, adopted the transfer matrix method (TMM) in cylindrical coordinates [36]. APCs offer low-loss (high Q-factor) resonators, making them suitable for chemical and biological sensing applications [37].…”
