The waveguide is designed to have a high Q structure. The filter has high power operation capability, low insertion loss, good passband standing wave characteristics, high out-of-band attenuation and good temperature stability, and is especially suitable for narrowband applications.
Waveguide instrument is a perfect combination of modern bioelectricity technology and meridian theory of traditional Chinese medicine. It not only gives full play to the advantages of acupuncture point stimulation, dredging meridians, regulating yin and yang, and balancing viscera, but also avoids the disadvantages of acupuncture, such as invasiveness and pain, and the inconvenience of moxibustion and microelectrode stimulation. It also takes into account the adjustment of human bioelectric balance system, and the physical therapy and health care effect is remarkable.
