Abstract: PROBLEM TO BE SOLVED: To realize a cold neutron lens based on refraction optics. SOLUTION: A cold neutron refraction lens system is constituted of an array of thin lenses. In a lens holder 18, 5 concave lens elements 11 are placed. The number of the lens elements 11 depends on the neutron focal distance of each element 11. Total focal distance is f=f0 /n, where n is the number of elements in the array and f0 is the focal distance of a single lens. The lens material has a small negative relative refraction factor n-n0 , where n0 is refraction factor (=1). Therefore, focusing element should be concave lenses and not convex lenses normally used in focusing wavelength of light. A preferable material have cold neutron absorption (determined as absorption of neutron of 10 angstrom) at 10 barn or less and restricted interference scattering cross sectional area for neutron of 2200 m/sec to be 3 fm or more.

Abstract: PROBLEM TO BE SOLVED: To provide an improved antenna and microwave transceiver. SOLUTION: An apparatus includes an object and one or more sensors located adjacent to or in the object. The object is formed of a material whose dielectric constant or magnetic permeability has a negative real part at microwave frequencies. The one or more sensors are located adjacent to or in the object and measure an intensity of an electric or a magnetic field therein.
