Hybrid finite element (FE) boundary integral (BI) analysis of infinite periodic arrays is extended to include planar multilayered Green’s functions. In this manner, a portion of the volumetric dielectric region ci~n be modeled via the finite element method whereas uniform multilayered regions can be modeled using a multilayered Green’s function. As such, thick uniform substrates can be modeled ...
A millimeter-wave (mm-wave) antenna with enhanced gain for new 5G networks is introduced in this work. rectangular slot operating at the fundamental mode of desired frequency band utilized study. The improved by employing a Frequency Selective Surface (FSS). FSS-based reflectors are designed same and added under specific distance to achieve required enhancement suitable dimension 25 × 5 ...
This is a prospective study to establish prediction models that map the refined Scoliosis Research Society 22-item (SRS-22r) onto EuroQoL-5 dimension 5-level (EQ-5D-5L) utility scores in adolescent idiopathic scoliosis (AIS) patients. Comparison of treatment outcomes in AIS can be determined by cost-utility analysis. However, the mainstay spine-specific health-related quality of life outcome me...
