charge(object,frequency) calculates
and plots the absolute value of the charge on the surface of an antenna
or array object surface at a specified frequency.

c = charge(object,frequency) returns
a vector of charges in C/m on the surface of an antenna or array object,
at a specified frequency.

[c,p] = charge(object,frequency)
returns a vector of charges in C/m on the surface of an antenna or array object,
at a specified frequency and at the point at which the charge calculation was
performed.

charge(object,frequency,'dielectric')
calculates and plots the absolute value of charge at a specified frequency value
on the dielectric face of the antenna or array.

c = charge(object,frequency,'dielectric')
returns the x, y, z
components of the charge on the dielectric surface of an antenna or array
object, at a specified frequency.

c = charge(___,Name,Value)
calculates the charge on the surface of an antenna using additional name-value
pairs.

Antenna or array object, specified as a scalar handle.

frequency — Frequency used to calculate charge distribution scalar in Hz

Frequency used to calculate charge distribution, specified as
a scalar in Hz.

Example: 70e6

Data Types: double

Name-Value Pair Arguments

Specify optional
comma-separated pairs of Name,Value arguments. Name is
the argument name and Value is the corresponding value.
Name must appear inside quotes. You can specify several name and value
pair arguments in any order as
Name1,Value1,...,NameN,ValueN.

Example: 'scale','log10'

'scale' — Scale to visualize charge distribution string (default) | function handle

Scale to visualize the charge distribution on the surface of the
antenna, specified as a string or a function handle. The string values
are: 'linear', 'log',
'log10'. By default, the value is
'linear'. The function handle can be of any
mathematical function such as log,
log10, cos, or
sin.

Complex charges, returned as a 1-by-n vector in C/m. This value is
calculated on every triangle mesh or every dielectric tetrahedron face on
the surface of an antenna or array. of antenna or array.

p — Cartesian coordinates representing center of each triangle in mesh 3-by-n real matrix

Cartesian coordinates representing the center of each triangle in the
mesh, returned as a 3-by-n real matrix.
