Novel ultra-compact 868 MHz/5GHz lowpass–bandpass diplexer for IoT

In this paper, we present a novel lowpass–bandpass diplexer designed to operate at frequencies of 868 MHz and 5 GHz. This diplexer is designed to overcome the limitations identified in previous studies. Notably, it achieves a maximum group delay of – 0.77 ns in the second passban...

A compact 2D photonic crystal biosensor for optical detection of glioblastoma brain tissues enhanced by neural networks

Abstract In this work, a compact optical sensor based on a two-dimensional photonic crystal is proposed for detecting glioblastoma and pre-tumor brain tissues. The sensor uses a hexagonal lattice of silicon rods in air with a ring resonator structure at its center. The designed d...
