A method to improve the directivity of the microstrip coupler is presented. The width of the coupler is modified for phase velocity compensation which results in high directivity. Using this procedure, a 15 dB coupler is designed and simulated at 0.9 GHz using SONNET software. A high directivity of 46 dB is obtained. The validity of the design concept is verified and compared with conventional ...

A hyperbolic bration is set of q ?1 hyperbolic quadrics and two lines which together partition the points of PG(3; q). The classical example of a hyperbolic bration comes from a pencil of quadrics; however, several other families are known. In this paper we construct a new family of hyperbolic brations for odd prime powers q. As an application of hyperbolic brations, we note that they can be us...

These 3 sonnets explore the lives of pop-star Irene Cara, author and Nobel Prize winner Octavio Paz, soccer legend Diego Maradona. Though one major sonnet form from literary history has included iambic pentameter, here drop part, but keep pentameter. In sonnet, there traditionally have been rhyme schemes. There is no particular scheme in these sonnets. They are written with a mixture free verse...
