An intraocular lens of novel structure exhibiting an excellent focus adjusting power. A hollow capsule structure is filled with a transparent liquid-like or gel-like filler (32). A front wall of the capsule structure is composed of a flexible lens front film (16), and a rear wall of the capsule structure is composed of an optical lens (18) having a diameter larger than that of the flexible lens front film (16). Under a state inserted into and attached to a capsula lentis, pressure variation of a corpus vitreum acts on the optical lens (18) to enable focal refraction power to be adjusted by utilizing swelling deformation of the lens front film (16).

The invention discloses a power-adjustable backward wave oscillator. The power-adjustable backward wave oscillator is characterized in that: by inserting upper and lower two rows of periodically complementary split-ring resonator structure into the middle part of a cavity of rectangular waveguide vertically, the complementary split-ring resonator structure has a relatively higher electric field resonant response at the slit of the opening, that is, between the horizontal branches of the two half parts, and shows the meta-material electromagnetic characteristic with a negative dielectric constant epsilon and a negative magnetic permeability Mu; longitudinal resonant field intensity is formed at the upper surface and lower surface of the periodically complementary split-ring resonator structure, thus being conductive to interaction between charged particles of band-shaped electron beams and electromagnetic waves; and at the same time, three electron beam channels are formed. Therefore, compared with a traditional relativism backward wave oscillator, the power-adjustable backward wave oscillator has higher coupling impedance and can obtain very high power output and electron efficiency. Besides, the structure enables one electron beam to work individually, or enables two electron beams or three electron beams to work, so that three kinds of adjustable power output of single beam, double beam and three-beam can be formed and then multi-band-shaped power can be adjustable.
