ABSTRACT:
The variational statement of synthesis problem is generalized in order to account
the additional requirements to the synthesized radiation pattern (RP)
and field distribution in the specified points of near zone. For this aim, the
minimizing functional is supplemented by term providing the possibility to
minimize the values of field in these points; creating the deep zeros in the RP
for the certain angular coordinates is realized too. The approach foresees reduction
of an explicit formula for field values in a near zone. The results of
computational modeling testify the possibility to create zeros in the given RP
and to minimize the values of field in a near zone of plane arrays in a great
extent.
