Abstract:
1. A method of producing a refractive element including one or more biaxial materials, comprising: identifying a first electromagnetic parameter of a first material corresponding to a selected first internal axis of the first material; identifying a second electromagnetic parameter of the first material corresponding to a selected second internal axis of the first material, the second electromagnetic parameter being related to the first electromagnetic parameter by a ratio β identifying a first electromagnetic parameter of a second material corresponding to a selected first internal axis of the second material, the second material being different material from the first material; identifying a second electromagnetic parameter of the second material corresponding to a selected second internal axis of the second material, the second electromagnetic parameter of the second material being related to the first electromagnetic parameter of the second material by a ratio β determining an orientation of the second material relative to the first material at which reflected energy for non-normally incident energy refracted at a boundary between the first and second materials is substantially zero; orienting the materials at the determined orientation; and joining the materials at the determined orientation.
