In this study, we explore the orientation of crystals formed within the lamellar domains of a diblock copolymer composed of two crystallizable blocks, that is, poly(l-lactide)-block-polyethylene (PLLA ...

A dual-band frequency-selective (FS) linear rotation polarizer leveraging a substrate-integrated waveguide cavity technology equipped with two perturbation techniques is introduced. The FS ...

A dual-band polarizer is presented that converts linear polarization into circular polarization with orthogonal handedness in the satcom bands 19.7–20.2 GHz and 29.5–30 GHz. The polarizer consists of ...
