The low tight bend-loss of antiresonant hollow-core fibers (AR-HCFs) is critical for many practical applications. In this paper, we provide an approximate analytical formula for the nested AR-HCFs to ...

The time-domain performance of a wearable UWB antenna under bending is presented in this paper. The system fidelity factor (SFF) is evaluated for a case where a cylindrical bending radius of 50 mm is ...
