example
hr = horn creates a standard-gain pyramidal horn antenna.
hr = horn(Name,Value) creates a horn antenna
with additional properties
specified by one or more name-value pair arguments. Name is the property name
and Value is the corresponding value. You can specify several name-value pair
arguments in any order as Name1,Value1,...,NameN,ValueN. Properties not
specified retain their default values.
