Expressing complex numbers in polar notation
There is a quick hack. But I want to know if there is a possible built-in function or other way. for example complex float ib= 218.0*cos(230.0*PI/180.0) + 218.0*sin(230.0*PI/180...

I have just built the circuit with a 10mH coil. but I only get response when the phone is ringing and the distance is only about 5cm! Adding the antenna has no effect!!!
