ON THE NEAR-FIELD SAMPLING AND TRUNCATION ERRORS IN PLANAR TIME-DOMAIN NEAR-FIELD TO FAR-FIELD TRANSFORMATION

On the Near-Field Sampling and Truncation Errors in Planar Time-Domain Near-Field to Far-Field Transformation

This paper studies the effect of three important parameters in planar time-domain (TD) near-field (NF) to far-field (FF) transformation. These parameters are the NF spatial sampling, NF measurement distance and scan surface truncation. The effect of these parameters over the TD FF accuracy are difficult to predict for Ultra Wide Band antennas. In this paper we aim to choose the optimum NF measu...

Seismic Behavior of Jacket Offshore Platform Subjected to Near and Far Field Ground Motions

Offshore structures such as jacket platforms have to inevitably be designed against  sever  environmental actions. In seismically active areas these structures also become susceptible to earthquake excitations. Strong ground motions recorded  in recent earthquakes, including the 1995 Kobe, Japan, 1999 Chi-chi, Taiwan and 1999 Kocaeli, Turkey earthquakes, revealed that the dynamic motions in nea...
