A Millimeter-Wave Dual-Band Substrate Integrated Waveguide Filter with Complementary Split Ring Resonators

This paper presents a millimeter-wave dual-band bandpass filter based on a substrate integrated waveguide (SIW). The dual-band response is realized by embedding two pairs of complementary split-ring resonators (CSRRs) with different dimensions in the SIW cavity. Their geometry-de...

Optical phased array LiDAR chips towards polarization-resolved 4D sensing

Optical phased array (OPA)-based LiDAR technology provides high-speed, solid-state sensing for autonomous vehicles, robotics, and aerial systems. However, current OPA-based LiDAR platforms lack the ability to accurately recognize and classify materials, limiting their effectivene...

Adaptive rocket trajectory optimization via reinforcement learning and FPGA acceleration

This paper presents an integrated framework for reusable rocket trajectory optimization that combines deep reinforcement learning with FPGA-based inference acceleration. The proposed Adaptive Hardware-Accelerated Twin Delayed Deep Deterministic Policy Gradient (AHA-TD3) framework...
