We successfully fabricate a polymer optical waveguide with multiple graded-index (GI) cores directly on a substrate utilizing the soft-lithography method. A UV-curable polymer (TPIR-202) supplied from Tokyo Ohka Kogyo Co., Ltd. is used, and the GI cores are formed during the curing process of the core region, which is similar to the preform process we previously reported. We experimentally conf...

The present paper gives a new computational framework within which radiative transfer in a varying refractive index biological tissue can be studied. In our previous works, Legendre transform was used as an innovative view to handle the angular derivative terms in the case of uniform refractive index spherical medium. In biomedical optics, our analysis can be considered as a forward problem sol...

Abstract In this paper, a new single negative metamaterial (MTM) unit cell structure with low profile of 6.2 × m 2 is proposed. The shows near zero refractive index (NZRI) characteristics in C, X and Ku bands whereas epsilon (ENG) Ku-Band frequency. properties the proposed MTM are analysed Rogers 5880 substrate which displays permittivity. To verify effectiveness split ring resonators (SRR) as ...
