Abstract：
 The invention discloses a negative refraction device with adjustable temperature which is based on dielectric particle and metal wire and a preparation method thereof. The device consists of a plurality of tiered PTPE template blocks, dielectric ceramic particles, metal wires and an attemperating apparatus. Each block of PTPE template is provided with an array of round holes, the dielectric ceramic particles and the metal wires are alternately embedded into the round holes to form an array of dielectric ceramic particles and an array of metal wires. The device can ensure that the electromagnetic wave to show isotropic negative magnetic conductivity when the magnetic resonance occurs during a certain frequency band, as well as a negative permittivity is showed simultaneously, thus realizing the negative index of refraction. The controllability of the negative permeability is achieved by temperature through the regulating property for the permittivity of dielectric ceramic particles thereof, and consequently the controllability of the negative index of refraction is achieved. The invention attaches the intelligent capability to the left-handed material, and the invention can be applicable to photoconducting devices such as an adjustable band-pass filter, a photonic crystal slab with adjustable negative index of refraction, and an adjustable hidden device, as well as to the communication field.
