I am Lao Wen, an embedded engineer who loves learning.Follow me to become even better together! I remember when I first started working, a master told me that if you are not familiar with longjmp and setjmp, you should not call yourself a C language expert. At that time, I was half-convinced, but to move … Read more

As the working frequency of DSP continues to increase, the design of power and ground has become increasingly important in high-speed DSP systems. This also raises higher requirements for electronic engineers. A reasonable design of power and ground not only affects system performance but also directly impacts the stability and reliability of the system. Therefore, … Read more
“The combination of surface coils and metamaterials significantly improves the performance of Magnetic Resonance Imaging (MRI), offering notable local enhancement flexibility. However, due to the coupling between the two, the signal-to-noise ratio (SNR) and low contrast resolution are hindered, further obstructing the future development of clinical MRI. This paper proposes a high-Q metasurface decoupling isolator, … Read more
