We report initially the design, fabrication and measurement of using waveguided electric metamaterials (MTM) in the design of closely-spaced microtrip antenna arrays with mutual coupling reduction. The complementary spiral ring resonators (CSRs) which exhibit single negative resonant permittivity around 3.5GHz are used as the basic electric MTM element. For(More)
Using simple optical equations we solved for the depth of field (or range of movement for clear viewing) of plus lenses and near telescopes of the same equivalent power and then compared them. The prevalent clinical wisdom states that reading telescopes have a smaller depth of field than plus lenses. Our results show depth of field to be equal for both and(More)
