Study about Resonance

I am now studying about resonance on transmission line.

Is there any recommendation on good study materials (books or any online materials) about the mechanism of resonance and the relationship between reflection (standing wave) as well as lambda/2? Further topics about resonance such as radiation(antenna theory), wave mode, etc...

What I knew about resonance is just about the LC elements that cause resonance. Would like to further my understanding by relating wavelength, multiples of half wavelength into resonance as well as other advanced topics.

Thanks for your help in advance.

Thank you for the link.

What I really hope is to know how to relate VSWR, half-wavelength to resonance. Their relationship is kind of vague to me.
Appreciate a lot if anyone could enlighten me on this.

Thanks.
